Algorithm
Built by nursing educators, powered by the same science as the real NCLEX.
1PL Rasch model with Maximum Likelihood Estimation — the same algorithm NCSBN uses for the real NCLEX exam.
Multiple Choice, SATA, and NGN questions across all 8 NCLEX test plan categories and 22 subject areas.
Questions get harder when you're right, easier when you're wrong. The engine finds your exact ability level.
95% confidence interval stopping rule — know your pass probability in real-time during the exam.
Every question has a detailed explanation for correct AND incorrect options. Learn why each answer is right or wrong.
The same Computer Adaptive Testing algorithm used by NCSBN for the real NCLEX exam.
Your exam begins at the passing standard (0.0 logits). The first question is at medium difficulty — right at the NCSBN passing line.
Answer correctly → next question is harder. Answer wrong → next question is easier. The engine uses Maximum Fisher Information to select the most informative question for your ability level.
Once the engine is 95% confident your ability is above or below the passing standard (after minimum 85 questions, SE ≤ 0.2695), the exam stops. Maximum 150 questions.
