Ms. Peters' school uses the RTI system to identify and support students who may be at risk of learning difficulties. As the classroom teacher, Ms. Peters understands that she is responsible for delivering strong Tier 1 instruction to her students.

Which of these is part of Tier 1 instruction?

A. Interventions at least three times per week for about 30 minutes each session
B. Regular, ongoing instruction to groups of one to three students
C. Daily, one-on-one instruction for students whose achievements are considerably behind their peers
D. Differentiated, core reading instruction that is delivered in the regular classroom setting

Tier 1 instruction in the RTI system involves providing differentiated, core reading instruction that is delivered in the regular classroom setting to all students. This means that the main instruction given by Ms. Peters to her students should cater to their diverse learning needs within the classroom.

It does not involve interventions like daily one-on-one instruction for students considerably behind their peers or targeted support multiple times per week. Instead, Tier 1 focuses on the foundational instruction that all students receive in the general classroom setting.
