Case Study Overview:
Scope | Grade 8 Math | 8-week tutoring cycle
Focus | NC EOG-aligned priority standards
Impact | Near 70th statewide percentile | 50% proficiency rate
Alamance Burlington 8th graders participating in Spring 2025 GROW 8-Week GROW Tutoring Cycle Demonstrated Strong State Assessment Outcomes (North Carolina End-of-Grade Assessments).
Participating students demonstrated:
In an exploratory matched-baseline review comparing students with similar Grade 7 starting scores, GROW participants also demonstrated higher observed Grade 8 statewide percentile performance and proficiency rates than matched non-GROW peers.
Grade 8 students participated in approximately eight weeks of targeted math tutoring prior to North Carolina EOG administration.
Instruction focused on high-priority Grade 8 standards and skills, including:
Students received standards-aligned small-group instruction designed to reinforce critical Grade 8 mathematical concepts during the spring testing window.
Spring 2025 comparison of Grade 8 students participating in GROW tutoring and non-participating peers across key NC EOG measures. On average, Grade 8 students participating in GROW tutoring performed near the 70th percentile statewide. Half of GROW participants reached Level 3 proficiency or higher; GROW students also had stronger representation in Level 4 achievement bands than non-GROW peers.
To provide additional context, a subset analysis compared: 20 Grade 8 GROW students with 20 non-GROW students who demonstrated similar Grade 7 baseline scale scores in 2024. GROW students demonstrated higher observed Grade 8 statewide percentile performance and higher proficiency rates than matched non-participating peers with similar Grade 7 baseline scale scores.
This analysis is descriptive and exploratory in nature. Participation in tutoring was not randomized, and findings should not be interpreted as causal evidence of program impact.
