The percent of Arizona 3rd grade students who scored Proficient or Highly Proficient on the AzMERIT 3rd grade English language arts assessment.
Third grade students in district and charter schools in Arizona.
AZM2 data for 2021were downloaded from the Arizona Department of Education’s (ADE) Accountability & Research website. County-level totals were filtered to show scores for the English Language Arts Grade three assessment. Students with scores in performance levels 3 and 4 (Proficient and Highly Proficient) were considered to have passed this assessment. The ADE report breaks down these scores by county and several demographic characteristics. To protect students’ privacy, ADE does not report cell counts that represent ten or fewer students. Also, to protect privacy, all cells of either zero or one percent are grouped together and reported as “*.”
Morrison Institute entered into a data use agreement with the Arizona Department of Education in order to obtain un-redacted 2021 AZM2English Language Arts Grade three assessment data. Students with scores in performance levels 3 and 4 (Proficient and Highly Proficient) were considered to have passed this assessment. The school level data were analyzed and aggregated to the county and municipal level without suppression rules. If cell counts were still less than 11 after aggregation to municipal or county level, then suppression rules were applied prior to reporting of the data. This analysis of data without suppression on the front end allowed for a more thorough understanding of AZM2 data in small municipalities.

For the un-redacted analysis, Morrison Institute entered into a data use agreement with the Arizona Department of Education in order to obtain un-redacted 2021 AZM2 data by school and LEA for English Language Arts Grade three assessment data which included number tested, percent passing, and percent at each proficiency level. The data were also provided by subgroups of interest including race, limited English Proficiency, income eligibility, and students with disabilities. Students with scores in performance levels 3 and 4 (Proficient and Highly Proficient) were considered to have passed this assessment. The number of students passing was calculated from the variables provided (number of students tested and percent of students passing). The school level data were analyzed and aggregated to the municipal and county levels by subgroup without suppression rules. Data were then suppressed (indicated with “*”) if the denominator (number tested) included fewer than 11 or passing rate percentage was less than 2% or greater than 98%. This analysis of data without suppression on the front end allowed for a more thorough understanding of AZM2 results in small municipalities.
To provide data to municipalities on local education conditions and trends, data that is usually released at the school or district level was converted to county and municipal level data. This process provides a picture of how both district and charter schools in a geographic area are performing.
In Arizona, school district boundaries do not necessarily follow city and town boundaries, and charter schools are free to locate where they please. Additionally, Arizona is an open-enrollment state, meaning that students can enroll in a school that is in a different town from where they reside, and there are an increasing number of online ‘virtual’ schools that may have an office in a certain city, but the students have no particular connection to the city. A final complication is that a school’s street address does not necessarily conform to the physical city in which it resides. For example, Marana High School is located within the Marana town limits. However, it has a Tucson street address even though the Tucson city limits are over 10 miles distant.
To resolve these conflicts, a shapefile containing the geography of Arizona municipalities (downloaded from the US Census Bureau) was imported into ArcGIS. This file contains the boundaries of incorporated cities and towns, as well as Census Designated Places (CDP), which are recognized unincorporated population centers such as Sun City and Mayer.
From the National Center for Education Statistics (NCES) the following were downloaded:
The latitude and longitude were used to map all schools in ArcGIS, and a spatial join was performed with the Census Bureau shapefile to determine the city, town, or CDP that each school is located in.
Schools that NCES identified as virtual schools were labeled as such and not assigned to any municipality.
Schools located on unincorporated county land and not in a CDP were individually examined, and assigned to a municipality based on the proximity of the school and district to neighboring areas.
Schools that were remote from population centers as defined by the Census Bureau are listed as “unallocated.”
