How is the National Police Test Score Calculated?
This calculator uses the official formula used in the National Police exams to calculate your score on the theoretical, psychotechnical and spelling tests. It's important to know this formula because it penalizes errors, deducting points for each incorrect answer.
Official National Police test formula
The official formula established in the National Police announcements is as follows. This formula applies to both theoretical and psychotechnical exams:
Score = [(C - W / (n - 1)) × 10] / T C = Correct answers
W = Wrong answers
n = Answer alternatives
T = Total questions
How to use the calculator?
- Enter the total number of questions on the exam (usually 100 in theoretical knowledge).
- Specify your correct answers: how many questions you answered correctly.
- Indicate your errors: how many questions you got wrong.
- Number of alternatives: indicate how many answer options each question has (usually 4 in psychotechnical and 3 in knowledge).
- Get your score! The calculator will apply the official formula and show your score out of 10.
Tips to improve in the tests
- Practice regularly: Take practice exams frequently to familiarize yourself with the format and improve your speed.
- Time management: Learn to distribute your time during the exam to complete all questions.
- Doubt = Don't answer: Since errors are penalized, only answer if you are reasonably sure. You can eliminate incorrect alternatives to increase your chances.
- Identify patterns: Pay attention to the types of questions that usually appear and develop strategies to address them.
- Calculate your minimum score: Know how many questions you need to get right to pass the cutoff score. This will help you set realistic goals.
Frequently Asked Questions
How is the National Police exam score calculated?
The official formula is: Score = [(Correct - Wrong/(n-1)) × 10] / Total questions. Where "n" is the number of answer alternatives. For example, in a 100-question test with 4 alternatives, if you have 70 correct and 10 wrong: [(70 - 10/3) × 10] / 100 = 6.67 points.
How much do errors penalize in National Police tests?
Errors penalize according to the formula: Wrong / (n-1), where "n" is the number of alternatives. In a 4-option test, each error penalizes 1/3 of a correct answer (0.33). In a 3-option test, each error penalizes 1/2 of a correct answer (0.50). That's why it's important to only answer when you have reasonable certainty.
How many questions are on the National Police theoretical exam?
The theoretical knowledge exam usually has 100 multiple-choice questions with 3 answer alternatives (A, B, C). The psychotechnical exam also has 100 questions but with 4 alternatives. Both exams have a time limit established in the announcement.
What score do I need to pass the National Police exam?
There is no fixed minimum passing score. A cutoff score is established that varies in each announcement depending on the number of positions and the scores of applicants. The cutoff score usually ranges between 5 and 7 points out of 10, but it can be higher. The important thing is to get the highest score possible to be among the best.
Do blank questions penalize in National Police exams?
No, blank questions (not answered) do not penalize. Only incorrect answers penalize. That's why the recommended strategy is: if you have doubts and can't eliminate incorrect options, it's better to leave the question blank than risk getting it wrong and losing points.
How can I practice to improve my score on National Police tests?
The best way to improve is: 1) Do frequent practice tests with the same structure as the official exam. 2) Practice time management to complete all questions. 3) Review mistakes and study topics where you fail most. 4) Use this calculator after each practice test to know your real score and adjust your strategy.
What is the difference between the knowledge exam and the psychotechnical exam?
The theoretical knowledge exam evaluates your knowledge of the official syllabus (laws, constitution, state organization, etc.) and usually has 3 alternatives. The psychotechnical exam evaluates mental aptitudes (reasoning, memory, attention, etc.) and usually has 4 alternatives. Both use the same scoring formula but with different numbers of alternatives.
Is it better to answer all questions or leave some blank?
It depends on your level of certainty. If you can eliminate one or more incorrect options, statistically it pays to answer. For example, in a 4-option test, if you eliminate 2 incorrect options, you have a 50% chance of getting it right. But if it's pure chance without eliminating options, it's better to leave it blank because the penalty exceeds the expected benefit.
