The blog post Revisiting the CS HS: Bigger, Richer, and More Suburban introduced several metrics that illuminated how well states supported CS in schools in rural areas, with higher free/reduced lunch rates, and smaller student populations. These school-based 2021 CS Ed Metrics were republished using Tableau dashboards in the post School-Based Metrics Dashboards (2021)
| Metric | Definition | 2021 Nat Avg | 2022 Nat Avg |
|---|---|---|---|
| Poor/Rich HS with CS Relative Strength | % schools with FRL > 50% offering CS / % schools with FRL < 50% offering CS | 76.5% | 76.7% |
| Rural/Urban HS with CS Relative Strength | % schools in Town or Rural offering CS / % schools in Urban or Suburban offering CS | 88.4% | 121.6% |
| Have Not/Have HS Size Ratio | Avg size of HS that does not offer CS / Avg size of HS that offers CS | 30.9% | 38.1% |
All of these statistics are based on data provided in the 2022 State of CS Education report published by Code.org, CSTA, and the ECEP Alliance and data on the 2022 AP CS exams from Barbara Ericson’s Computing for Everyone blog.
The changes in the national averages from 2021 to 2022 in the rural/urban stat and the school size stat are significant and will be investigated further at a later date.
Note that 2022 state-specific dashboards published in early 2023 used AP data from 2021. However, as AP data for 2021-22 became available in April 2023, future posts on 2023 will use this cleaner and better synchronized data instead.
Two other school-based metrics appearing below are % HS with CS and % Students in HS with CS. Both of these metrics are covered in great detail in the 2022 State of CS Education report and are not included below.
