Education Statistics Data: Dataset Structure and Field Coverage

NAEP answers a single formatted GET. The verified pattern is GetAdhocData.aspx?type=data&subject=writing&grade=8&subscale=WRIRP&variable=GENDER&jurisdiction=NP&stattype=MN:MN&Year=2011, which returned JSON with serviceVersion 6.4.2026.1: mean writing scale scores of 139.10 for male and 158.57 for female eighth-graders in the national-public sample. Each result row carries year, subject, grade, scale, jurisdiction, variable, value, isStatDisplayable and errorFlag, and subscales follow documented codes such as MRPCM for the mathematics composite. Two operational notes: parameter documentation lives on the API documentation page rather than a developer portal, and nces.ed.gov itself was serving a "Service Disruption" placeholder during review even though nationsreportcard.gov and its API stayed fully operational.

Explore Education Statistics is the more conventional REST design, documented at api.education.gov.uk/statistics/docs. Three calls cover most needs:

1. GET /v1/publications?page=1&pageSize=2 lists releases - page one showed 23 publications including 'Pupil absence in schools in England'.
2. GET /v1/publications/{id}/data-sets returns each data set with latest-version metadata: geographic levels, filters, indicators, time periods.
3. GET /v1/data-sets/{dataSetId}/csv streams the full data set - a verified pull of the absence file returned 497 KB of rows carrying time_period, geographic_level, la_name, absence_type, enrolment_count and enrolment_percent from 2006/07 to 2024/25.
