Academically, Standley Lake High School's performance is generally on par with district and state averages, with some areas of strength and weakness. While the school's 11th-grade students scored 66% proficient or better in SAT Reading and Writing, they scored only 29% proficient or better in SAT Mathematics, lower than the district and state. In PSAT9 assessments, Standley Lake's 9th-graders performed better than the district and state in Reading and Writing, but lower in Mathematics. The school's four-year graduation rate has been relatively stable, ranging from 83.1% to 89.6% in recent years, which is in line with district and state averages.

Compared to nearby schools within the same district, such as Arvada High School and Arvada West High School, Standley Lake High School generally performs better academically. However, when compared to high-performing schools outside the district, such as Monarch High School (part of the Boulder Valley School District) and Jefferson Academy High School, Standley Lake's academic performance lags behind. The school also faces challenges with high chronic absenteeism rates and achievement gaps among different student subgroups, which are areas the school is working to address.
