How are multi-select questions (multiple-choice questions that require students to choose more than one correct answer) scored?

An example of a multi-select question would be, “Which TWO of the following answer choices best captures a main idea from the poem?” On these types of questions, students get full credit for getting both answers right, half credit if they choose one correct answer, and zero credit if they choose neither of the right answers.

If a student chooses only one answer choice instead of two, the student will get half-credit if the answer that he or she chose was one of the two correct answers, or zero credit if they chose neither of the two correct answers.

Alternatively, if the student selects more than two answers, he or she will receive zero credit for the question, regardless of whether or not he or she selected any of the correct answers.
