What’s on the Exam?
There are 91 questions on the exam, which are grouped into four competencies, and the time limit is 4 hours and 45 minutes.
The questions are split into two types:
90 questions
Selected-response questions require you to select the correct answer from a list of options. Multiple-choice questions are the most common example, but you may also see true-or-false questions and “matching” questions, which ask you to match terms or concepts with their definitions.
Constructed-Response (CR)
1 question
The constructed-response question requires you to write your answer instead of selecting from a list of choices. Your response to this question is generally expected to be 400-600 words, and you’ll be given specific details and instructions before you take the test.

Computer-Adaptive Testing (CAT)
The TExES Educational Diagnostician exam is a computer-adaptive test. Basically, this means that the questions will become harder or easier as you go through the exam, based on how well you’re answering the questions.
For example, say you answered the first question correctly. The first question is of medium difficulty, so the next question will be slightly harder. Then, let’s say you answered the second question incorrectly. The next question would then be a medium question.

Exam Scores
The test is scored using a scaled scoring method. Here’s how it works:
You will need a score of 240 to pass the test.
The reason your raw score is converted to a scaled score is because everyone who takes the test is given a slightly different set of questions. Since everyone has a different arrangement of questions, and because some questions are harder than others, converting your raw score to a scaled score ensures a more even playing field.
