Enem: check the maximum and minimum grades for the 2022 edition of the exam

To the National High School Exam (Enem) scores have minimum and maximum values due to the way they are calculated. The evaluation system used in Enem is called Item Response Theory (IRT), an advanced statistical methodology.

In this sense, TRI evaluates not only whether candidates' answers are correct or wrong, but also the consistency of the answers in relation to the difficulty of the questions.

In practice, this means that a candidate's score is not only based on the number of questions correct, but also on the difficulty level of the questions they got right and wrong.

Enem maximum and minimum grades vary each year

Because of its peculiar evaluation system, the minimum and maximum grades for the Enem tests may vary from one year to the next.

The maximum marks represent the highest score a candidate can achieve in the test, while the minimum marks are the lowest possible score.

Such variations occur because the TRI takes into account the distribution of candidates' skills and the level of difficulty of the questions in a given edition of the exam.

In this context, the minimum and maximum grades are calculated based on these factors, and are not fixed values.

Consequently, this means that the maximum and minimum scores adjust to each edition of the Enem, thus reflecting the performance of the candidates and the complexity of the questions in that specific year.

It is important to note that, while the minimum and maximum grades may vary, the Enem scoring scale for most tests is from 0 to 1,000 points. In the case of essay, the scale is from 0 to 1,000 points, with specific evaluation criteria.

Therefore, IRT is an approach that aims to make the assessment fairer, taking into account the difficulty of the questions and the candidates' performance in relation to this difficulty.

The National Institute of Educational Studies and Research Anísio Teixeira (Inep) released the minimum and maximum grades for each subject in the 2022 Enem, held on November 13th and 20th of that year:

• Natural Sciences: minimum of 308.7 points and maximum of 875.3 points;
