MTSS for MLs

The ESEA, as amended by the ESSA, recognizes the unique instructional needs of MLs. Core language instruction has been mandated through the federal judicial system and is monitored by the OCR. The SCDE realizes that identified MLs have differing needs based on their success in learning academic English. 

Once students enter a core content area class, they may need ELD and other types of support that must be included in everyday classroom instruction. For MLs, these may consist of accommodations to the instructional activities, tasks, and assessments. As MLs attain fluency in English, however, fewer accommodations and direct ML services may be necessary. 

MLs at lower levels of proficiency and/or with an educational background of limited or interrupted instruction may require additional support, accommodations or modifications, and/or multiple classes of support in the beginning. 

MLP services are not intervention services; they are direct instructional services for MLs, also considered part of their Tier I instruction and supplemental to the general curriculum. Therefore, MLP services and accommodations should be treated with the same importance as any other core instruction. All MLs with an English proficiency level of ‘1.0-6.0’ or ‘A1-A3,’ as well as monitored students (M1-M4), if determined by the MLPT, must have an ILAP that specifies language accommodations on file, reviewed, and signed by team members. 

The ILAP is a legally binding document similar in importance to an IEP or a 504 plan. The Supreme Court case Lau v. Nichols (1974) and subsequent legislation from the Equal Education Opportunity Act (1974) obligate school districts to provide MLs with meaningful and equal access to the curriculum. ILAPs contain pertinent information about each ML and the specific accommodations to meet their needs. All teachers that serve the student must follow the specifications outlined in the ILAP. 

MLs should be considered the same as any other students eligible for any program that will help them reach the same standards of performance asked of all students. Evaluations and services may not be delayed because of a student’s proficiency level in the English language.  Once students enter a core content area class, they may need language development and other types of support that must be included in everyday classroom instruction. For MLs, these may consist of accommodations to the instructional activities, tasks, and assessments. As MLs attain fluency in English, however, fewer accommodations may be necessary. 

The number of MLs in South Carolina districts and schools varies widely throughout the state, and services for these students are also quite variable. In addition, those identified as MLs include students with different individual needs. MLPTs should be formed to support decisions for MTSS. MLPTs include stakeholders invested in ML’s education. This team may include guardians, content teachers, MLPS/teacher, administrators, counselors, speech-language pathologists (SLP), special education teachers, school psychologists, and students. MLPTs should consider the following general guidelines in determining MTSS services for MLs beyond Tier I instruction with all appropriate accommodations and modifications: 

It is critical to ensure that MLs have access to the general education curriculum and appropriate MLP supports based on language development levels. 

SC Tier I (Universal) Instruction for Multilingual Learners 

Tier 1 is… 

Multilingual Learner Program are direct instructional services for multilingual learners; 

Appropriate, effective, and research-based core instruction for all students (reading, writing, math, social-emotional learning); 

A process that includes formal, universal screening that occurs at least three times a year,focusing on specific skills, strategies, and content knowledge; 

 A process that includes formal and informal progress monitoring on an ongoing and continuous basis; 

Instruction with specific adaptations and modifications based on assessment and progress monitoring; 

Targeted, intense instructional support within the classroom for all students who may have difficulty; 

A variety of flexible, grouping configurations for instructional practice; and/or 

A team approach with teachers, administrators, and parents working collaboratively. 

Tier 1 is not… 

Multilingual Learner Program services are not intervention services; 

Core instruction in which some students are successful and others are not, and this is perceived as the reality; 

In-class assessments that focus primarily on what is taught rather than what students know and are able to do; 

Only about determining student progress every nine weeks and at the end of the school year; 

One-size-fits-all instruction; 

Reliance on other instructional support staff (e.g., special education and MLP staff) to determine a student’s needs and to provide remediation; 

Whole class instruction, or fixed instructional groups consisting of students who are high, average, and low achievers; and/or 


Teachers who work primarily on their own. 

When a collaborative problem-solving team considers the need for Tier II strategic or supplemental interventions for a multilingual learner, the team should consider the following questions: 

1. Have multilingual learners had sufficient opportunity to learn (quality of instruction and reasonable time), with consideration of educational background? 

2. Does Tier I instruction reflect high-quality, differentiated best practices where the language and literacy teaching is appropriately scaffolded? 

3. Are meaningful opportunities for students to practice in the four language domains (listening, speaking, reading, and writing) implemented? 

4. Are our teachers respectful and supportive of multilingual learner students’ cultures and language learning needs, and culturally relevant principles applied to instruction and assessment? 

5. Are we committed to using only research and evidence-based interventions? 

6. Have appropriate accommodations been implemented with fidelity? 

7. How will we determine the fidelity of implementation (e.g., data-driven decisions) 

8. Prior to Tier II considerations, has collaboration taken place between specialists in language acquisition and/or other related school staff? 

SC Tier II Interventions for Multilingual Learners 

Tier II is… 

Supplemental instruction in addition to the Multilingual Learner Program; 

Supplemental instruction (in addition to the core grade level instruction); 

Focused and targeted to specific skills in small groups that are associated with broader academic and behavioral success; 

Designed for students who are not making adequate progress on core skills that are associated with broader academic and behavioral success; 

Explicit instruction that emphasizes key instructional features we know to be important for multilingual learners: opportunities for developing and practicing oral language, key vocabulary emphasis, interaction, learning strategy instruction, etc.; and/or 

For approximately 20-25% of the students in a given class, grade level, or school. 

Tier II is not… 

Multilingual Learner Program services are not intervention services; 

A replacement of the core curriculum; (Note: If students are not getting the core curriculum, they will only fall further behind.) 

Time to reteach an academic standard(s) or behavioral strategy that students did not master; (Note: These students need to receive differentiated instruction in Tier I.) 

Designed for students who did not master a specific standard or behavioral strategy; (Note: These students need to receive differentiated instruction in Tier I.) 

A replacement for Multilingual Learner Program services; and/or 

For more than 30% of the students in a given class, grade level, or school. This reflects inadequate Tier I instruction. 

When collaborative problem-solving teams discuss the need for intensive Tier III intervention for a multilingual learner, the team should consider the following questions: 

1. Are we giving our multilingual learners sufficient time, adjusted interventions, and support in Tier II before considering Tier III? 

2. Are the teachers providing the Tier II interventions highly qualified in their content areas and have educator knowledge of the second-language acquisition process and the role of language proficiency? 

3. Is the intervention using information based on ML’s proficiency level and co-developed with the support of an MLPS/teacher? 

4. Is the intervention differentiated, high-quality language and literacy instruction with varying levels of intensity? 

5. Is the intervention research-based or evidence-based? For more information on research-based/evidenced-based interventions, visit the following: 

a. National Center on Intensive Intervention.

ii. Evidence-Based Practices (Part 2): Implementing a Practice or Program with Fidelity 

iii. Evidence-Based Practices (Part 3): Evaluating Learner Outcomes and Fidelity 

6. Are there criteria for successful responses to the intervention, such as rate and amount of growth and/or time in Tier II? 

7. Have decisions been data-informed and appropriate for instructional adjustments? 

8. Does the intervention lay out a plan for implementation, and is it captured somewhere to review if it was delivered as it was intended (e.g., the fidelity of implementation)? 

9. Are the progress monitoring probes appropriate for multilingual learners? Do they contain a language bias that may be affecting the data? 

10. Have culture and specific language learning needs been considered? 

11. Has the multidisciplinary team considered queries in the guidance from the South Carolina Standards for Evaluation and Eligibility Determination (SEED)? 

SC Tier III Interventions for Multilingual Learners 

Tier III is… 

Multilingual Learner Program is direct instructional service for multilingual learners; 

Intensive instruction that promotes learning and remediates skill deficits targeted to a child’s individualized needs. It is more intensive than Tier II. 

It is an instruction that is: 

• systematic and explicit with many opportunities for student participation and practice of desired skill; 

• characterized by increased frequency of targeted instruction in even smaller homogenous groups provided by teachers trained in the specific intervention instruction; 

Intended for a specific duration of time using frequent progress monitoring to inform ongoing decisions about the effectiveness of intervention and placement; 

Part of the MTSS framework which allows for fluid movement between tiers depending on the documented need for support; and/or (Note: Students continue to receive Tier I core instruction for most of the school day even if they receive intensive Tier III intervention in small groups outside of the general education classroom.) 

Data from intensive intervention can be used to support the identification as a child with a learning disability. The data can show patterns of strengths and weaknesses over time. This data will provide evidence that the student, having been provided evidence-based instruction for multilingual learners, targeted at specific skill deficits by a teacher with expertise in literacy and English language development, may need special education services due to a learning disability. 

Tier III is not…

 Multilingual Learner Program services are not intervention services; 

Simply more of the same instruction students receive in the core; 







An indefinite Tier III intervention; 



A way to remove challenging students from general education or a direct pathway to special education; and/or 



Special education, but intensive general education intervention. 

An effective data-based decision-making system for MLs includes the following: 

1. Screening and progress-monitoring measures with established validity and reliability with MLs. 

2. Educator knowledge and use of students’ language proficiency data when interpreting student achievement data. 

3. Regular review of student data for the purposes of planning instruction. 

4. Collaborative evaluation of student progress and instructional planning within all tiers of instruction.
