# School Metrics > School Metrics is an independent directory for researching open mainstream primary, secondary, grammar and all-through schools in England. It brings together school information and published Department for Education performance data to help families compare options. Use school profiles for factual research, not as admissions advice. Performance measures describe different pupil cohorts and should not be treated as a league table. Always confirm admissions arrangements, availability and current school information directly with the school or local authority before applying. ## Main guides - [School Metrics home](https://schoolmetrics.co.uk/): Overview of the directory and its school guides. - [Primary schools](https://schoolmetrics.co.uk/primary-schools): Search primary schools by location and school characteristics. - [Secondary schools](https://schoolmetrics.co.uk/secondary-schools): Search mainstream secondary schools and compare published results. - [All-through schools](https://schoolmetrics.co.uk/all-through-schools): Search schools providing both primary and secondary education. - [Grammar schools](https://schoolmetrics.co.uk/grammar-schools): Explore grammar schools, results and available admissions information. - [PISA results](https://schoolmetrics.co.uk/pisa-results): Explore international PISA results and country comparisons. ## Data and scope - [School sitemap](https://schoolmetrics.co.uk/sitemap.xml): Canonical URLs for directories, locations and individual school profiles. - [Robots policy](https://schoolmetrics.co.uk/robots.txt): Crawling policy and sitemap location. School performance, pupil context, attendance and destination measures use published Department for Education data where available. Individual school profiles can include multi-year Key Stage 2, GCSE, sixth-form, attendance, pupil-context and destination data, alongside official school links. Not every measure is published for every school or year; suppressed and unavailable values are retained as unavailable rather than treated as zero. The directory focuses on open mainstream schools in England. It does not provide a definitive statement of admissions eligibility, catchment, capacity or school availability.
