Third-grade reading tests for achievement standards such as the National Common Core standards typically cover vocabulary, reading comprehension, interpretation and reading to perform tasks. The tests consist of stories and passages of text followed by questions about what the student has just read.
Vocabulary questions usually require the student to choose a word similar in meaning to one in the text. Reading comprehension involves simply recalling details and finding the answers to a question in the passage. Interpretation questions do not have direct answers in the reading; the student must use reasoning to determine the best answer. These are often "Why?" questions or questions that ask which of the multiple-choice answers best answers the question. A task-oriented question may require the student to derive answers by reading information from a chart.
