2018 DC School STAR Scores and Performance Ratings

District of Columbia's 2018 School Report Card provides STAR performance scores and ratings for 203 schools based on the 2017-18 school year. The dataset includes overall STAR scores on a 0-100 scale and star ratings from 1 to 5. Metrics are calculated from applicable framework scores and student groups, with scores suppressed for groups smaller than 10 students.

Use Cases

• Analyze the distribution of STAR scores (0-100) and star ratings (1-5) across 203 DC schools to identify performance tiers.
• Compare performance between different school frameworks (e.g., Elementary vs. Middle School) for schools with non-traditional grade configurations.
• Investigate the impact of student group n-size thresholds on reported STAR scores, as metrics are excluded for groups with fewer than 10 students.
• Correlate school-level STAR scores with teacher data reported for high-poverty and low-poverty schools as defined in DC's ESSA State Plan.

Strengths

• Covers 203 schools that received a STAR score and rating for the 2017-18 academic year.
• Provides a standardized 0-100 STAR score and a 1-5 star rating for each school based on multiple framework metrics.
• Includes detailed methodological documentation via the official 2018 DC School Report Card and STAR Framework Technical Guide.
• Data is sourced from the District of Columbia's Office of the State Superintendent of Education (OSSE), an authoritative government body.

Limitations

• Data is from a single academic year (2017-18), limiting longitudinal trend analysis.
• Metric scores are not reported for student groups with an n-size less than 10, which may obscure performance details for small populations.
• Two schools that closed after the 2017-18 year (Excel Academy PCS and Washington Mathematics Science Technology PCHS) do not have full report card metrics calculated.
