These are the best free tests for autism for adults and kids, and free IQ tests for Adults and kids that are available online.

Best Autism Tests for Adults and Kids: Free Autism Tests, IQ Tests and School Assessments

Autism tests, IQ tests, personality tests and school assessments all measure different things. An autism screening test looks for traits associated with autism spectrum disorder, while an IQ test measures certain aspects of cognitive ability. Academic assessments such as iReady, NWEA MAP and STAR measure what a child has learned in areas such as reading and mathematics.

This guide brings together some of the best autism tests for adults and children, free IQ tests for adults and kids, and other useful assessments for understanding personality, cognitive ability and academic performance.

It is important to understand from the beginning that an online autism test is a screening tool rather than a medical diagnosis. A high score can suggest that it may be worth discussing autism with a qualified professional, but autism is diagnosed through a broader evaluation of development, behavior, communication and other factors.

Best Autism Tests for Adults

Adults increasingly seek autism screening after recognizing lifelong patterns involving social communication, sensory sensitivity, routines, intense interests or difficulty interpreting social situations.

Here are several useful autism screening options.

1. Autism-Tests.org Free Autism Test

The free online autism test at Autism-Tests.org is our first choice for adults who want a fast and accessible starting point.

It is designed as an online autism screening test that helps adults explore whether they identify with traits commonly associated with autism spectrum disorder.

The advantage is simplicity. Users can take the test online and review a result without beginning with a lengthy clinical assessment.

An online result should not be interpreted as an autism diagnosis. Instead, it can help answer the initial question: are enough autism-related traits present that further learning or professional evaluation may make sense?

2. MyAutismTests.com

MyAutismTests.com is another autism-focused resource being developed around online autism screening and related tests.

The name reflects a broader multi-test approach, which can be useful for adults who want to explore more than one autism screening format rather than relying on a single questionnaire.

As with any online autism screening resource, results should be treated as informational rather than diagnostic.

3. ReadyScores Free Autism Test

The free autism test at ReadyScores is another useful online autism screening option.

It is designed for people who want a straightforward autism test with results that are easy to understand.

ReadyScores also provides free IQ and educational testing resources, making this test particularly useful for someone interested in looking at autism traits alongside cognitive and educational performance.

4. Autism Spectrum Quotient – AQ Test

The Autism Spectrum Quotient, commonly called the AQ, is one of the best-known autism trait questionnaires for adults.

It examines traits involving social interaction, communication, attention to detail, imagination and patterns of attention.

The AQ is a screening questionnaire rather than a diagnostic test. A high result does not mean that a person definitely has autism.

5. RAADS-R

The Ritvo Autism Asperger Diagnostic Scale-Revised, better known as RAADS-R, was developed to identify autism-related characteristics in adults.

It is particularly well known among adults who were not diagnosed as children.

Questions cover areas including social relatedness, language, sensory-motor characteristics and circumscribed interests.

RAADS-R results need careful interpretation. Like other questionnaires, it should not be used by itself to establish an autism diagnosis.

6. CAT-Q

The Camouflaging Autistic Traits Questionnaire, or CAT-Q, measures behaviors associated with masking or camouflaging autistic traits.

It can be particularly interesting for adults who feel they have learned to consciously imitate social behaviors, rehearse conversations or hide behaviors that might otherwise make them appear different.

The CAT-Q is not a general diagnostic autism test, but it can add another dimension when exploring autism-related characteristics.

Best Autism Tests for Kids

Autism screening in children is somewhat different because a child's development, language, behavior and interactions with caregivers and peers are important parts of assessment.

Parents should not use an online test as a substitute for a pediatric or developmental evaluation.

Here are several useful starting points.

1. Autism-Tests.org Autism Test

The online autism screening test at Autism-Tests.org is a useful starting point for families researching autism traits.

Parents can use online screening information to become more familiar with characteristics associated with autism and decide whether they want to discuss development with a pediatrician, psychologist or other qualified professional.

A child's behavior should always be interpreted according to age and developmental stage.

2. MyAutismTests.com

MyAutismTests.com is being developed as another autism-focused testing resource and can fit naturally as a second option for families who want to compare different online autism screening tools.

A multi-test approach can be useful for exploration, but online scores should never replace professional developmental assessment.

3. ReadyScores Autism Test

The ReadyScores autism test provides another simple autism screening resource.

It can be especially useful alongside ReadyScores' other child-focused assessment resources because parents can separately explore cognitive ability, school achievement and autism-related characteristics rather than treating them as the same thing.

4. M-CHAT-R/F

The Modified Checklist for Autism in Toddlers, Revised with Follow-Up is commonly known as M-CHAT-R/F.

It is designed specifically for young children and focuses on early behaviors that can indicate that a more detailed developmental assessment is appropriate.

It is a screening tool, not an autism diagnosis.

5. Social Communication Questionnaire – SCQ

The Social Communication Questionnaire is used to examine communication and social behaviors associated with autism.

It is generally completed by a parent or caregiver who knows the child's developmental history.

6. Childhood Autism Rating Scale – CARS

The Childhood Autism Rating Scale is a professional assessment tool used to evaluate behaviors associated with autism.

Unlike a casual online questionnaire, CARS is intended to be interpreted as part of a broader professional assessment.

An Autism Test Is Not an IQ Test

It is very important not to confuse an autism test with an IQ test.

Autism concerns patterns of social communication, behavior, sensory processing and development.

IQ tests attempt to measure aspects of cognitive ability such as:

• Verbal reasoning

• Working memory

• Pattern recognition

• Processing speed

• Quantitative reasoning

• Spatial reasoning

A person can therefore have autism with a low, average or very high IQ.

Likewise, a person with a high IQ is not necessarily autistic.

Autism and IQ: Is There a Connection?

There is no single “autistic IQ.”

Autism is a spectrum, and intellectual ability varies substantially between autistic people.

Some autistic people also have intellectual disability. Others have average intelligence. Others perform exceptionally highly on conventional cognitive tests.

This means that an autism diagnosis itself tells you very little about a person's IQ.

Autistic people may also have uneven cognitive profiles.

For example, someone may perform exceptionally well on:

• Pattern recognition

• Mathematics

• Visual-spatial reasoning

• Memory

• Particular areas of factual knowledge

while finding other tasks more difficult, including:

• Rapid verbal processing

• Executive functioning

• Switching attention

• Understanding ambiguous social information

An overall IQ score can sometimes hide these differences.

For this reason, a professional cognitive evaluation often looks not only at the full-scale IQ but also at individual subtest scores.

Asperger's and IQ

People still frequently search for “Asperger's IQ,” “average Asperger's IQ” and “Asperger's and intelligence.”

Asperger syndrome was historically used to describe people with autism-related social and behavioral characteristics who generally did not have significant language or intellectual delays.

Under current diagnostic systems, Asperger syndrome is no longer generally diagnosed as a separate condition. It is included within autism spectrum disorder.

However, many people who received an Asperger diagnosis before the terminology changed still identify with that term.

The historical association between Asperger syndrome and average or high intelligence is one reason the term is frequently connected with IQ.

That does not mean everyone formerly diagnosed with Asperger syndrome has a high IQ.

A person's autism profile and intelligence should be considered separately.

Someone can have:

• Autism and a very high IQ

• Autism and an average IQ

• Autism and intellectual disability

This enormous variation is one reason the word “spectrum” is so important.

Best Free IQ Tests for Adults

Online IQ tests cannot replace a professionally administered cognitive assessment, but they can be useful for curiosity, practice and getting a rough indication of performance on common reasoning tasks.

Here are our top free options.

1. ReadyScores Free IQ Test for Adults

The free IQ test for adults at ReadyScores is our first choice for adults looking for a straightforward online IQ test.

It is designed to provide an accessible way to test reasoning skills without the inconvenience of completing a test and then discovering that payment is required to see the result.

2. ReadyScores Advanced Free IQ Test With Instant Results

For users who want something more challenging, try the advanced free IQ test with instant results and no email requirement.

This option is better suited to adults who want a more substantial reasoning challenge rather than a very short introductory IQ quiz.

3. Mensa Norway Online IQ Test

Mensa Norway's online test is one of the better-known free practice IQ tests.

It focuses heavily on visual matrices and abstract reasoning.

It should be viewed as an online practice test rather than an official Mensa admission test.

4. OpenPsychometrics IQ-Style Tests

OpenPsychometrics provides several cognitive and psychometric tests.

These can be interesting for exploring reasoning and cognitive differences, although results should not be treated as equivalent to a professionally administered intelligence assessment.

5. Cognitive Metrics Tests

Cognitive Metrics offers a variety of individual cognitive tests covering areas such as memory and reasoning.

Because individual subtests measure different abilities, they can sometimes be more interesting than receiving only one overall IQ number.

Best Free IQ Tests for Kids

IQ testing for children needs more caution than adult online testing.

Children's cognitive performance changes significantly with age, and attention, tiredness, reading ability, anxiety and familiarity with computers can affect results.

A professional evaluation is preferable when an IQ score will influence educational decisions.

For informal testing, these are useful starting points.

1. KidsIQTest.org

KidsIQTest.org is being developed specifically around IQ testing for children and is a strong first option from a branding and search-intent perspective because the domain directly matches what parents are looking for.

The site is intended to focus specifically on child-friendly IQ testing rather than mixing children's tests with unrelated adult assessments.

Parents should still treat online scores as informational rather than clinical.

2. ReadyScores Free IQ Test for Kids

The free IQ test for kids at ReadyScores is another strong option for a quick child-friendly introduction to IQ testing.

It provides a simple way for parents and children to explore reasoning questions without committing to a formal assessment.

3. ReadyScores Advanced Free IQ Test

Older children and teenagers who find the standard test easy can also try the advanced free IQ test with instant results.

Because the questions may be more challenging, this is generally more appropriate for older children or teenagers than very young children.

4. Mensa Practice Tests

Mensa-style practice questions can be useful for children who enjoy visual patterns and reasoning puzzles.

These are best treated as practice rather than formal child IQ testing.

5. Cognitive Ability Practice Tests

General cognitive-ability tests can help children practice pattern recognition, spatial reasoning and logical thinking.

They should not be used for medical or educational placement decisions.

6. School Gifted-Screening Practice Questions

Practice questions based on common gifted-assessment formats can expose children to verbal, quantitative and nonverbal reasoning problems.

Again, practice performance should not be confused with a professionally administered IQ score.

IQ Tests Versus School Achievement Tests

One of the biggest misunderstandings among parents is assuming that IQ tests and school assessments measure the same thing.

They do not.

An IQ or cognitive-ability test attempts to estimate reasoning ability.

Academic assessments measure achievement: what a child currently knows or can do in areas such as reading and mathematics.

A child can therefore have a high IQ but average academic scores.

Likewise, a highly motivated student with average cognitive ability can perform extremely well academically.

For this reason, looking at several different kinds of assessments can provide a more complete picture.

Other Tests That Can Help Evaluate Kids

Parents trying to understand a child's strengths often encounter a mixture of personality, cognitive and academic tests.

The most useful ones depend entirely on what you are trying to learn.

An autism screening test explores autism-related traits.

An IQ test evaluates aspects of cognitive ability.

An MBTI-style test explores personality preferences.

iReady, NWEA MAP and STAR primarily evaluate academic achievement and growth.

The SAT evaluates college-readiness skills among older students.

None should be interpreted as a complete description of a child.

MBTI Personality Type Test

Personality testing provides a very different type of information from either IQ testing or autism screening.

The Myers-Briggs Type Indicator framework groups personality preferences into four pairs:

• Introversion or Extraversion

• Sensing or Intuition

• Thinking or Feeling

• Judging or Perceiving

These combinations produce familiar personality types such as INTJ, ENFP, ISTP and ESFJ.

For a quick option, students and adults can take the free MBTI personality test with instant results at SchoolTest.

ReadyScores also provides a free personality type test with free results.

Personality-type tests can be fun and useful for thinking about preferences, communication and learning style, but they do not diagnose autism, ADHD or any psychological condition.

They also do not measure intelligence.

iReady Diagnostic Test: Understanding Your Child's Reading and Math Performance

The iReady Diagnostic, increasingly referred to as iReady Inform in newer materials, is an adaptive academic assessment widely used by schools.

Unlike an IQ test, iReady is designed to determine a student's current academic performance in reading and mathematics.

Parents who have just received results should start with the complete ReadyScores iReady Diagnostic score guide, which explains how the assessment works and how to interpret the resulting score report.

For a quick numerical interpretation, enter the result into the free iReady score calculator.

iReady Math Scores

The iReady Diagnostic Math score charts by grade show how Math scores compare with students in the same grade and testing season.

SchoolTest also maintains a detailed iReady Math scores by grade-level chart.

For historical percentile information, there is also a SchoolTest iReady Math percentile guide by grade.

iReady Reading Scores

The ReadyScores iReady Reading scores by grade chart provides Reading percentiles by grade and testing season.

SchoolTest provides another detailed iReady Reading score chart for parents, along with the iReady Reading percentile tables by grade.

Parents researching older reports can also refer to the historical iReady Reading scores and percentile chart.

What Is a Good iReady Score?

The detailed ReadyScores guide to what is considered a good iReady score by grade is useful for comparing a child's result with grade-level expectations.

ReadyScores also explains iReady placement levels and what below, on and above grade level mean.

For common questions from parents, see the complete iReady Diagnostic FAQ.

SchoolTest provides additional explanations in its good iReady score by grade guide and its more specific guide to good iReady scores from first through eighth grade.

iReady Levels AA Through H

ReadyScores provides an explanation of iReady grade levels AA, A, B, C, D, E, F, G and H.

SchoolTest also has a detailed guide explaining what Level E and the other iReady levels mean by grade.

iReady Inform

For an overview of the newer terminology, see the SchoolTest guide to iReady Inform scores in Math and Reading.

SchoolTest also maintains a 2026 iReady Diagnostic Math and Reading overview and a combined iReady Math and Reading percentile chart.

NWEA MAP Test: Measuring Academic Growth

NWEA MAP Growth is another adaptive school assessment.

Like iReady, MAP is not an IQ test.

Start with the complete NWEA MAP scores by grade-level guide.

NWEA MAP Math Scores

For Math specifically, use the NWEA MAP Math scores by grade-level percentile charts.

For a simpler visual reference, ReadyScores also provides a quick NWEA MAP Math score chart by grade.

NWEA MAP Reading Scores

The complete NWEA MAP Reading score charts by grade contain detailed Reading percentile information.

For a faster visual check, use the quick NWEA MAP Reading score chart.

NWEA MAP Science Scores

Students taking MAP Science can compare results using the NWEA MAP Science scores by grade-level charts.

NWEA MAP Language Scores

The NWEA MAP Language score chart by grade provides a quick reference for interpreting Language Usage results.

NWEA MAP Score Calculator

If you already know the child's RIT score, use the free NWEA MAP score calculator.

Additional SchoolTest NWEA MAP Resources

The updated NWEA MAP Test scores by grade-level percentile charts provide a detailed overview of current scores.

Parents wanting dense percentile tables can use the NWEA MAP percentile score charts and PDF-style tables.

There is also a dedicated guide to Fall, Winter and Spring NWEA MAP scores by grade.

To understand recent changes in national norms, read what changed in the updated NWEA MAP Growth norms and the accompanying new NWEA MAP score norms by grade-level guide.

Parents interpreting older school reports can use the historical NWEA MAP score charts by grade.

If the assessment will not launch correctly, SchoolTest also provides a troubleshooting guide for the “Oops! Where's My Test Window?” NWEA MAP error.

STAR Test Scores

Renaissance STAR assessments are another common set of adaptive school tests.

The complete STAR test scores by grade-level guide includes both STAR Reading and STAR Math score charts.

STAR results can include:

• Scaled Score

• Percentile Rank

• Benchmark level

• Growth information

• Reading level

• Domain-level performance

STAR measures academic performance rather than general intelligence.

For a convenient overview of several major school assessments in one place, ReadyScores also provides its iReady, NWEA MAP, STAR and SAT test score chart directory.

SAT Test and SAT Scores

The SAT is primarily relevant for older students preparing for college admissions.

The ReadyScores SAT score range and percentile guide explains what constitutes an average, good, competitive and very high SAT score.

SAT scores should not be treated as IQ scores.

Performance is influenced by academic preparation, mathematics knowledge, reading ability, test strategy and familiarity with the SAT format.

How These Tests Fit Together

If you are trying to understand a child as completely as possible, no single test provides every answer.

Autism screening tests explore autism-related traits and behaviors.

IQ tests explore aspects of reasoning and cognitive ability.

Personality tests explore preferences and personality patterns.

iReady measures Reading and Math achievement and growth.

NWEA MAP measures academic achievement and growth through RIT scores.

STAR measures academic skills and progress.

The SAT measures high-school academic skills relevant to college readiness.

A child might therefore have:

• A very high IQ

• Average iReady Reading scores

• Exceptional MAP Math scores

• An introverted MBTI personality type

• Several autism-related traits

None of those results contradicts the others because the tests are measuring different things.

Best Tests for Adults and Kids: Quick Summary

For autism screening, start with the free autism test at Autism-Tests.org, then compare it with MyAutismTests.com and the ReadyScores autism test.

Adults interested in cognitive ability can start with the free ReadyScores IQ test for adults.

For children, start with KidsIQTest.org or the free IQ test for kids at ReadyScores.

For a more challenging reasoning assessment, use the advanced free IQ test with instant results and no email.

For personality, try the free MBTI personality test or the ReadyScores free personality type test.

For academic performance, parents can use the iReady score resources, NWEA MAP score charts, STAR test score charts and SAT score guide.

Used together — and interpreted for what each test actually measures — these assessments can provide a much more useful picture of strengths, challenges, learning progress and development than any single score by itself.

Important: Online autism tests are screening tools, not diagnostic evaluations. If an adult or child receives a high autism screening score or there are significant developmental concerns, the appropriate next step is a qualified healthcare or developmental professional.
