Final answer:
Tier 3 reading instruction is a highly individualized, intensive instructional level for students with significant reading difficulties, often involving one-on-one interventions, whereas Tier 2 is less intensive and typically involves small-group interventions.
Step-by-step explanation:
Tier 3 reading instruction is a more intensive and individualized form of support compared to Tier 2 reading instruction. While Tier 2 offers small group interventions for students who are struggling, Tier 3 reading instruction is often one-on-one and tailored to the specific needs of the student. This level of instruction is provided to students who have not made adequate progress in Tier 2 or those who are identified with a reading disability or severe reading difficulties. The focus at this level is on individualized assessment, more frequent progress monitoring, and interventions that target the student's specific deficits in reading.
Unlike Tier 2, which involves regular classroom instruction with some additional support, Tier 3 typically involves specialized instruction outside of the general classroom. These services are generally delivered by a reading specialist or special education teacher. The goal of Tier 3 reading instruction is to accelerate the student's reading development and help them catch up to grade-level expectations.
