Chemistry questions by performance level

Every released Regents chemistry question on this wiki, sorted by the performance level description (PLD) it best matches. NYSED publishes five PLDs for each standard that describe what students at each performance level can do; this page lists, for each chemistry standard and each level, every released question that assesses it, so you can look at a level and see all of the questions that fall under it.

Questions come from the June 2026 and August 2026 Regents Examinations in Physical Science: Chemistry and the sample clusters released by NYSED. Each standard page shows the same mappings as e.g. examples under its PLDs. Notice! — the mappings are editorial judgments, not official NYSED assignments.
