Grade 8 students performed near the 70th statewide percentile and achieved 50% proficiency on NC EOG Math

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:

• higher statewide percentile rankings,
• higher proficiency rates,
• and stronger representation in advanced achievement bands on the Grade 8 North Carolina EOG assessment.

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.

About the Tutoring Program

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:

• transformations and similarity,
• exponents and scientific notation,
• irrational numbers and roots,
• the Pythagorean Theorem,
• coordinate geometry,
• and volume applications involving cones, cylinders, and spheres.

Students received standards-aligned small-group instruction designed to reinforce critical Grade 8 mathematical concepts during the spring testing window.

Grade 8 NC EOG Outcomes (Spring 2025)

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.

Exploratory Matched-Baseline Review

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.

Important Context

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.
