The Certified Nursing Assistant (CNA) exam score range can vary depending on the specific format and evaluation criteria set by the state or the organization administering the test. However, the scoring for the CNA exam typically involves a pass/fail outcome for both the written and skills components. Here's a general overview of how these are assessed:

Written Examination
Scoring: The written part of the CNA exam usually consists of multiple-choice questions, typically ranging from 60 to 100 questions. Each question has one correct answer, and each correct answer contributes equally to the total score.

Passing Score: Most states require a passing score of 70% to 80%, but this can vary. For example, if the exam has 70 questions, you might need to answer approximately 49 to 56 questions correctly to pass, depending on the specific passing threshold set by the state.

Clinical Skills Test

Scoring: The clinical skills test is evaluated based on your ability to perform designated nursing tasks correctly and safely. You are generally asked to perform 3 to 5 selected skills from a possible set.

Criteria: Each skill is assessed against a checklist of critical steps. The evaluator marks each step as done correctly, incorrectly, or omitted. Failing to perform one or more critical steps correctly typically results in failing the entire skill.

Passing Criteria: To pass the skills test, you must successfully execute all assigned skills, adhering to all critical steps outlined in the assessment checklist. This means practically perfect execution is often required for each skill.

Combined Scoring

Certification: You must pass both the written and the clinical skills components to become certified. If you pass one part but fail the other, you will generally need to retake only the part you failed.

Retake Policies: States and testing agencies may limit the number of times you can retake the exams or may require additional training after a certain number of unsuccessful attempts.

For the exact scoring range and passing criteria, it's best to refer to the guidelines provided by the certifying authority in your state or the organization conducting the test, as these details are specific to each jurisdiction.
