How do I use this calculator?
Compare a reported official GACE scaled score with the selected threshold, or plan raw points and correct answers. Raw planning does not predict an official scaled score. Check the requirements for your exact assessment and provider, including applicable individual testlet floors.
Calculator Operations:
- Official score comparison: Enter the cumulative scaled score on your official report and select its assessment standard. Historical ETS profiles are labeled separately; the comparison alone does not establish certification status.
- Raw performance: Enter scored selected-response correct and total questions plus your own raw percentage target. Optional written points are added without weighting; blank written fields mean zero.
- Correct answers needed: Enter the scored question total and a raw percentage target. Add written points if relevant. The result rounds required selected-response answers upward and checks whether the target is attainable.
Use the calculate button when all known values have been entered and use the reset button when you want to clear the values from the calculator.
Compare an official GACE scaled score with current or clearly labeled historical thresholds, or plan unweighted raw points toward your own target. This calculator does not convert raw scores to official scaled scores.

Percent Correct (Raw Score) Formula
The following formula calculates your percent correct (raw score percentage):
Variables:
- PC is percent correct (%)
- CA is the number of correct answers
- TQ is the total number of scored questions
Percent correct is not an official GACE scaled score. With optional written work, this calculator uses raw percent = (correct answers + written points earned) / (scored questions + written points possible) × 100. Each selected-response answer counts as one point and written points are unweighted. Official scoring may use different weights, rubrics and equating; no linear raw-to-scaled estimate is provided.
What is a GACE Score?
The GACE score is a standardized scaled score used for educator assessment in Georgia. The testing supplier changed from ETS to Evaluation Systems, Pearson on July 1, 2025; scores and assessment parts from the two suppliers are not interchangeable. GaPSC established 220 on the 100–300 scale for content, service, paraprofessional and literacy assessments, and 250 for upgrade and educational leadership assessments, effective July 1, 2025. Applicable individual testlet floors must also be met. Historical ETS content tiers used 220 for induction and 250 for professional level. ASLPI, ethics and portfolio assessments use different scoring systems and are excluded from this tool. Confirm the exact requirements and result on your official report.

How to Plan a Raw GACE Practice Target?
The following steps calculate an unweighted raw practice percentage. They do not estimate an official scaled score:
- First, determine the number of correct answers (CA).
- Next, determine the total number of scored questions (TQ).
- Compute percent correct: PC = (CA / TQ) × 100.
- For written work, add earned written points to CA and possible written points to TQ in this unweighted planning model. Compare the result with a raw target you choose; do not substitute a scaled threshold such as 220 or 250.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Number of correct answers (CA) = 75
Total number of questions (TQ) = 100
Percent correct = (75 / 100) × 100 = 75%
With no written points, 75 correct out of 100 scored questions gives 75% raw performance. For an 80% raw planning target, 80 correct answers are needed. Neither result predicts an official GACE scaled score.
Standards reviewed: October 20, 2026. Current and historical provider profiles were checked against GaPSC testing information and GaPSC’s adopted scoring standards. A cumulative score at the selected threshold does not by itself confirm the required testlet floors or certification eligibility.
