When I am discussing RTI with educators many seem to believe that the RTI model is special education. In a research article titled The Blurring of Special Education in a New Continuum of General Education Placements and Services, Fuchs et al. (2010) describes that the meaning of RTI is interpreted differently by regular education teachers and those who provide support for at-risk students. General education teachers usually reflect the RTI model through the lens of the No Child Left Behind (NCLB) Act (2002)/Every Student Succeeds Act (ESSA) (2015). Those working in general education usually define RTI as “a reformed service delivery that emphasizes early intervention and the unification of general education and special education, which in turn facilitates adoption of challenging standards and accountability for all” (Fuchs et al., 2010, p. 304). General education teachers support collaboration among teachers to improve student learning and focus more on assessment and instruction than cognitive abilities. This group also emphasizes problem solving and differentiated instruction.
Whereas the educators supporting students at-risk, such as resource, speech, special education, etc. view the RTI model through the lens of the Individuals with Disabilities Education Act (IDEA) (2004). Their view defines RTI as a model to promote early intervention and to increase the validity of identifying students who may have a learning disability (Fuchs et al., 2010). Educators supporting students at-risk place more value on cognitive, linguistic, and perceptual data to inform the type of intervention treatment. Educators working with at-risk students believe that students who are unresponsive to instruction in Tier 2 should be evaluated by a multidisciplinary team using student data. Fuchs et al. also noted that educators supporting at-risk students recognize that instruction should be evidence-based, explicit, and top-down or researcher determined. This group usually relies more on student data and effective research-based interventions.
The RTI model was designed for educators to develop a multitiered instructional system to deliver standards-based, grade-level, student-supported curricula and instruction based on the current needs of present students and the resources available to support the RTI model at their school. A healthy RTI model should reach most struggling students, freeing-up special education services for students who have the most severe learning needs.
I described a typical RTI model in an October 2018 blog post as having three tiers of instruction, some may have more.
- Tier 1 instruction is taught using research-based curriculum and instruction that is differentiated to meet student learning needs. Tier 1 takes place in the general classroom, taught by a regular classroom teacher. Tier 1 should meet the learning needs of 80% of the students. Students who are struggling to meet the expectations of Tier 1 are referred for Tier 2 instruction, using universal screeners and classroom data. Students can skip tiers to better match individual learning needs.
- Tier 2 instruction becomes more intense using explicit systematic instruction based on student learning needs. Tier 2 instructions can be taught by regular classroom teachers, paraprofessionals, reading specialist or special education teachers. Tier 2 instructions typically take place outside of the regular classroom, in a small group setting. Students are progress monitored, usually once a week to ensure that the curriculum and the intensity of instruction are meeting student learning needs. Data from monitoring is used to adjust curriculum and instruction. Students not showing progress after a specified time at Tier 2 are referred for Tier 3 instruction.
- Tier 3 instruction becomes more intense and individualized. Some students may need more diagnostic testing to better pinpoint their particular learning needs. Tier 3 is usually taught in one-on-one settings by a paraprofessional, reading specialist or special education teacher. Tier 3 in some models is special education.
Each tier of the RTI model typically has a team of educators that support the instruction and movement of students in and out of that tier. Team members usually include the regular classroom teacher, reading specialist, special education teacher, and or the RTI liaison. Team members may also include administrators, parents, community liaisons, and other educational professionals, such as speech pathologist or psychologist.

Students write the letter, then say the sound. Or the teacher says the sound the student writes the letter. The third strategy is using sand. Colored maybe a better choice as this usually gives a better contrast and students tend to like color. Pour just enough sand to give about a fourth of an inch layer on a plate, on a table or on deep cookie sheet type container. Students write a letter in the sand and say the sound(s) of the letter. Or the teacher says the sound of the letter the student writes the letter. The fourth strategy is using pudding. This can be used in the same manner as the sand. This is a different texture. The fifth strategy is using play dough. Students use the play dough to form a letter(s). Students point to the formed letter
and say its sound(s). The teacher can ask students to form letters by uttering its corresponding sound. Students can use pictures of the letter to help them form the letter. The sixth strategy is using music. Using video that includes sound that students can sing-a-long with or mimic increases the number of senses that students use. Using video that includes motions, along with music and pictures can increase the retention of letter and sound correspondences. The last strategy that I will included in this blog is using a grate (usually plastic). The grate is usually
about the size of a piece of paper. The texture should be defined enough that when you place a piece of paper over it you can run a crayon over it to create a picture of the grate. The grate can be used in a few ways. Students trace the letter with their index finger, while saying its sound. Students place a piece of paper on the grate and write a letter using a crayon. Students then say the letters’ corresponding sound(s).
