1. What’s on the test & how many raw points does each part carry?

PartItem type & numbersRaw points% of total
A35 multiple‑choice (Q 1‑35)3541 %
B‑115 multiple‑choice (Q 36‑50)1518 %
B‑215 one‑credit constructed response (Q 51‑65)1518 %
C20 one‑credit constructed response (Q 66‑85)2023 %
TOTAL85 raw pts100 %

Percentages based on the 85‑point structure confirmed for the June 2025 administrations. nysed.gov

2. Who scores each part & what rubrics are used?

PartWho scores itScoring rules
A & B‑1 (MC)Optical scanner or hand counter1 pt per correct answer; no guessing penalty. nysed.gov
B‑2 & C (constructed)A committee of at least two certified chemistry teachers; each sees only about half of a student’s open responsesEach question worth 0 or 1 pt. Teachers use the statewide Rating Guide that includes sample correct solutions, diagrams, sig‑fig guidance, etc. nysed.gov

Safeguards:

  • Teachers may not score their own students’ papers.
  • Schools may not rescore open‑ended items once each has been rated the required number of times.

3. Converting your raw score (0‑85) to a scale score (0‑100)

NYSED releases a new conversion chart for every test date to “equate” difficulty. For June 2025 (still the most recent publicly released chart), a few landmarks were:

Raw totalScale score

6885
6077
4460
2232

How to use it on exam day

  1. Add the points you earned in Parts A + B‑1 + B‑2 + C (max = 85).
  2. Find that raw total in your administration’s chart.
  3. Read across to the scale score column—that is the number entered on your transcript.

Because every chart is a little different, never use an old one when calculating June 2025 or January 2026 results. nysed.gov

4. Passing, mastery & other cut scores

Scale scoreWhat NYSED calls itDiploma impact
65–100“Passing” (Performance Level 3+)Counts toward a standard Regents diploma.
55–64Approved safety‑net pass (IEP‑designated students)Counts toward a local diploma.
85+“Mastery in Science” benchmarkCan help earn honors or mastery endorsements.

5. Why the scale score isn’t a straight percentage

The conversion chart compensates for slight differences in test difficulty. That’s why two people who both earn, say, 60 raw points in June 2025 and August 2025 might get different scale scores. Item statistics (classical & Rasch) are analyzed after every administration to keep 65≈“equivalent performance” over time. nysed.gov

6. Lab‑hour requirement (gateway to sitting the exam)

Before a student may even take the Chemistry Regents they must document 1 200 minutes (30 × 40‑min periods) of satisfactory lab work. Schools keep lab reports for six months after the exam. nysed.gov

7. Quick strategy tips for students

  1. Harvest easy MC points first (Parts A & B‑1 = 50 raw pts). You’ll usually net these faster per minute than open responses.
  2. Know your reference tables cold. A third of the constructed items cue specific table values.
  3. Show work in B‑2 & C even for 1‑pt questions. Units, formulas & significant figures matter—raters can dock the point for sloppy work.
  4. Manage time: 3 hrs total. Many teachers suggest ~60 min for 50 MC, ~35 min for B‑2, ~50 min for C, 15 min review.
  5. Double‑check calculator mode & sig figs—avoidable slip‑ups sink 1‑pt constructed items.

FAQ

Do wrong multiple‑choice answers subtract points?

No—there is no penalty for guessing, so answer every question.

Can I bring a reference table?

Yes—the official NYSED Chemistry Reference Tables are provided; you may bring your own clean copy but the proctor will supply one.

How accurate is this calculator?
