Chart a Path to Proficiency with Stretch Growth®
Stretch Growth: A Research-Backed Recovery Metric
What will it take to achieve student proficiency over time? i-Ready’s growth measures provide some insight. Data gathered across millions of students over time who take our assessment informs our individualized student growth targets. This determines their individual placement level and unique growth goals to work toward getting to grade level.
Stretch Growth was created to support educators in setting an ambitious, attainable, and accelerated path to grade level for each student.
Our latest research shows more students—including those multiple years below their given grade level—can reach grade level by setting and meeting Stretch Growth targets two years in a row. Across all grades—including grades critical for learning (i.e., Grades 2 and 3 for reading and Grades 4 and 5 for mathematics)—we found:
- More students who placed two or more years below grade level reached grade level if they met Stretch Growth targets versus students who met Typical Growth in both years
- Even meeting Stretch Growth in one year accelerated more students to grade level than two consecutive years of Typical Growth
Percentage of Students On Grade Level after Two Years of Meeting Growth Goals:
