For time-sensitive information, use eduKateSG to understand the issue, then verify the current fact with the authority that controls it. This applies especially to syllabuses, examination dates, registration rules, admissions, school arrangements, public policy, prices, schedules, office-holders, and other information that can change.
Check three things: when the statement was written or last reviewed, whether the underlying fact is still live, and which organisation has authority to confirm it. A newer article is usually preferable to an older one, but the authoritative current source matters more than publication date alone.
For Singapore education matters, start by distinguishing independent explanation from official authority at Is eduKateSG an Official MOE Website?. For publisher identity, read Who Publishes eduKateSG?. For the wider freshness rule, read How Current Is the Information on eduKateSG?. Return to Research & Inquiry when the problem is evidence, uncertainty or source quality rather than a single live fact.
