Score Estimator

An unofficial NAVLE estimate tool built around transparent assumptions.

This is not an official ICVA predictor. It is a planning tool based on approximate item-response logic, visible assumptions, and honest uncertainty bands.

Important: Official NAVLE scoring is proprietary. Use this tool for range estimation and study planning only, not as a guarantee of passing.

Exam Assumptions

Set the structure and difficulty assumptions first.

360
60
Scored questions 300
60%
Four-option questions 40%
Weighted guessing floor 0.22
-0.8
+0.1
+1.2
Default assumptions are tuned to mirror the old estimator logic, but they remain approximations because official item parameters are not public.

Performance Input

Choose the input style that best matches how you tracked your exam.

80
80
30
Use this mode if you have a reasonable sense of how you performed across easier, moderate, and harder questions. It is the more direct input method.

Estimated Outcome

Use the range, not just the headline number.

425
Above passing range

Estimated confidence range: 390 - 460

200 425 pass threshold 800
Correct 0
Raw Percent 0%
Theta 0.00
Margin vs 425 0
