2 Breakdown of the HSPE First attempt offered during the students’ sophomore year 75 multiple-choice questions 60 core multiple-choice questions 15 field test items Questions are constructed at three Depth of Knowledge levels (DOK 1-3)

3 DOK 1 The question requires recall and there is nothing to “figure out” The student either knows the answer or they do not DOK 2 The student needs to apply information Typically multi-step Recall info, then decide what to do with that information DOK 3 Includes DOK level 1 and 2 processing Requires the student to decide how to approach the problem Make a prediction or inference while providing a justification
