Content standards
Editorial and content review policy
The standards used to source, align, explain, validate, publish and correct TNPSCLab's bilingual learning material.
Last reviewed: 29 August 2026
Source-first learning articles
Articles must be tied to retained, reviewable educational sources. Source links or citations are displayed within the article when available.
Bilingual alignment
English and Tamil versions must preserve the same examinable meaning. A translation is not treated as a separate factual source.
Immutable official PYQ keys
Official answer keys are never silently changed. If wording is ambiguous or another option is defensible, the explanation identifies the official key and states the ambiguity without inventing support.
Publication gates
Draft or structurally invalid material is not made searchable. Published learning content must pass source, bilingual, route, metadata and duplication checks.
Responsible use of automation
Tools may assist extraction, organization or drafting, but automation alone does not authorize publication. Source identity and deterministic validation remain required.
Updates and corrections
Material is updated when a meaningful source, syllabus or factual change is verified. Updated dates reflect substantive content changes, not cosmetic refreshes.
Report a content concern
Include the page URL, the exact sentence or question, and a reliable supporting source. We will review the report without silently changing official PYQ keys.
