First working version of the site.
Published to web.
Added 2024/25 data to the tool.
Added provisional 2025/26 enrolment data, later superseded by final Department of Education figures.
School pages now load much faster, especially when viewing a specific school.
Redesigned homepage and geography navigation with county-first exploration, plus stacked national and county trend charts for total enrolment, total schools, and average school size.
Extended national, county, and school trend charts with historical enrolment data back to 1974 where available; added school address metadata, a known data issues page, clearer hover-only chart labels, shorter year ticks, and dotted gap indicators for missing 1983/84-1992/93 source data.
Added an Irish-medium provision explorer with national aggregates by Irish classification and Gaeltacht status, including drill-down school lists and trend charts for each group.
Added verified mainstream class-size insights from 2006/07 to 2025/26, shown separately from enrolment-by-standard data on the homepage, school pages, county pages, and Irish-medium pages with clear source limitation notes.
Replaced the provisional 2025/26 enrolment workbook with final mainstream school data, including by-standard class breakdowns and updated national, county, Irish-medium, and school trends.
