To make shorter District-Based PD hours count toward recertificatioin, you can "bundle" several small activities together, provided they meet these conditions:
Topic Consistency: The activities must all be related to the same specific topic or theme.
Accumulated Minimum: The combined total of the bundled activities must reach at least 10 hours.
Demonstrated Mastery: According to DESE Guidelines, to count bundled hours, you must complete an additional follow-up activity (such as a reflection, an assessment, or a classroom application project) that demonstrates your proficiency in that topic.
