Analyzing Student Data:
RTI Model Student Progress Monitoring Scenario
Student Name: Janet
Age: 9
Grade: 4
Janet is currently a fourth grader at Bellmont Elementary School. Janet’s teacher, Ms. Clay, began adding Tier 2 instruction for her after Janet’s Lexile reader measure level was 545L in the seventh week of the school year compared to the average peer Lexile level of 790 in her class. This score confirmed the concerns of Ms. Clay regarding Janet’s difficulty with reading comprehension. Ms. Clay has been monitoring her progress using district-wide curriculum-based measurements. After 10 weeks of Tier 2 instruction (mid-school year), Janet’s Lexile Stretch goal is 605L and her expected rate of growth (slope) is 5.0.
The school-based student support team met last week to review Janet’s progress following the Tier 2 instruction that had been implemented. The purpose of the meeting was to determine what tier of instruction would best meet Janet’s current educational needs in reading comprehension based on the progress monitoring data that was collected. The team analyzed progress and compared Janet’s current reading levels to those of same-age peers to determine if she has been responding to the targeted Tier 2 instruction. After reviewing the results, the school-based student support team members disagree about what tier of instruction should now be used to further develop Janet’s reading comprehension skills and help her reach grade level on the Lexile assessment.

Using the slope calculator or calculating on paper to determine rate of progress (slope) for Janet, it is determined that her slope is 4.44 with a goal of 5.0.
Subtract first and last score: 590-550 = 40
Subtract the week of instructions: Week 10-Week 1 = 9
Divide the score by the result of the week of instruction: 40/9 = 4.44
Janet’s slope is 4.44
