Directions for Grade 3 I-Checks
The Grade 3 I-Check assessment is made up of multiple choice questions, constructed response
questions and performance questions.
Read each question carefully, including diagrams and/or graphs.
Work as rapidly as you can without sacrificing accuracy. Do not spend too much time puzzling over
a question that seems too difficult for you. Answer the easier questions first; then return to the
harder ones. Try to answer every question, even if you have to guess.
Where necessary, you may use scratch paper for your work. Do not use the margins of the test
booklet to do scratch work.
FOR ALL QUESTIONS, YOU MUST RECORD ALL OF YOUR ANSWERS ON THE TEST
BOOKLET.
