2021-2022 Letter Grades

On October 31st, the Arizona State Board of Education released the 2021-2022 A-F School Letter Grades for all public schools statewide. These reports provide information about student achievement, college and career readiness, student growth, and other key areas of interest to families and the general public.​

We are pleased to share our letter grades and data with the Higley community and are incredibly proud of our hard-working students and educators. All of our schools achieved an A or B letter grade for 2021-2022, rating them as excellent or highly performing by the Arizona State Board of Education, with eight of our schools receiving an A.

Why do Schools Get Letter Grades?

The A-F Letter Grade system is a requirement per Arizona Revised Statute (ARS 15-241) that requires the Arizona Department of Education, subject to final adoption by the Arizona State Board of Education, to develop an annual achievement profile for every public school in the state based on an A-F scale.

It is intended to be used by districts and schools to improve student outcomes, provide families with information on how their school is performing, and to help identify schools that may be in need of support.

The system measures student achievement, annual growth, and student readiness for whatever is next in their education or career.

What does a Letter Grade Mean?

A (Excellent)
Distinguished performance on the statewide assessment, significant student growth, high four-year graduation rates, students on track to proficiency; overall performance is significantly higher than state average.
B (Highly Performing)
High performance on statewide assessment and/or significant student growth and/or higher four-year graduation rates and/or moving students to proficiency at a higher rate than the state average.
C (Performing)
Adequate performance but needs improvement on some indicators, such as proficiency, growth, or graduation rate.
D (Minimally Performing)
Inadequate performance in proficiency, growth and/or four-year graduation rate relative to the state average.
F (Failing)
Systematic failures in proficiency, growth, and graduation rates (below 67%); performance is in the bottom 5% of the state.

Student Growth Percentiles (SGP) describe how a student grows on a current year test in relation to current year students with the exact same prior year test scores.

SGPs of students are classified into three levels ranging from low to high and points are then assigned using a weighted measure using the student’s category and their prior-year achievement level.

Current-Year Student Growth Percentile
Prior-Year Achievement Level Weights
Highly Proficient 0 1.00 1.00
Proficient 0 1.00 1.20
Partially Proficient 0 1.00 1.80
Minimally Proficient 0 1.00 2.00
