Description: Participants complete an online Canvas course to prepare for item cluster writing. During the interactive course, participants: 

• learn how performance expectations (PEs) are bundled for the Washington Comprehensive Assessment of Science (WCAS);
• learn how phenomena are used in item clusters;
• learn how stimuli and items are written to form an item cluster for a PE bundle;
• learn how items and clusters are aligned to the three-dimensional science standards; and
• explore the WCAS online training tests.
