How to Use Diagnostic Assessments?
Given at the start of a unit or year; results guide grouping and support strategies.
Examples and Tools
CORE Screeners
What: Diagnostic tool for early reading skills (phonemic awareness, phonics, fluency).
Why: To find gaps and guide targeted instruction.
How: Administer individually, review results, group or adjust instruction.
ESGI (Education Software for Guiding Instruction)
What: A one-on-one digital assessment platform for early learners (typically TK–2) that checks literacy, math, and more.
Why: Gives quick data with auto-generated reports and allows progress monitoring in real time. Perfect for setting up small groups in primary grades.
How: Assess students 1:1 using a tablet; use data to group and monitor growth.
Fluency Checks
What: Timed reading assessments (usually 1 minute) used to measure accuracy, speed, and expression with grade-level text.
Why: Identifies fluency concerns and monitors reading progress. Can signal comprehension or decoding issues.
How: Have students read aloud for 1 minute; track WCPM to monitor reading progress.
Dyslexia Screening
What: A screener used to flag students who may be at risk for dyslexia, often checking phonological awareness, rapid naming, and letter-sound knowledge.
Why: Early identification allows for faster interventions and support.
How: Follow district protocol early in the year to flag students for early reading risk.
