The school is part of the Green Technical High Charter School District, which is ranked 828 out of 874 districts in New York and has a 0-star rating from SchoolDigger.

Green Technical High Charter School consistently ranks in the bottom 10-15% of New York high schools, with a ranking between 1,061 and 1,198 out of 1,207 to 1,242 high schools over the past 8 years. The school has received a 0 or 1-star rating from SchoolDigger, indicating very poor academic performance compared to other schools in the state. The school's performance is particularly low for certain student subgroups, such as African American students, Hispanic students, special education students, and low socioeconomic status students. Additionally, the school has struggled with high chronic absenteeism rates, ranging from 31.5% to 97.7% in recent years, which is much higher than the state average.

When comparing Green Technical High Charter School to nearby public high schools, such as Maple Hill Junior/Senior High School, Troy High School, Shaker High School, and Bethlehem Central Senior High School, the performance gap is significant. These nearby schools consistently outperform Green Technical High Charter School across a variety of metrics, including academic achievement, graduation rates, and college readiness. The school's challenges are exacerbated by the high concentration of economically disadvantaged students it serves and its proximity to other low-performing schools in the Albany area, such as Albany High School.
