What type of professional development is likely to have the greatest impact on teacher performance?

The option that is likely to have the greatest impact on teacher performance is a hybrid online and in-person six-week course that meets weekly for a cohort of teachers. This form of professional development combines the benefits of both online and face-to-face learning.

Engaging in a cohort allows teachers to collaborate, share insights, and establish a community of practice, which can enhance motivation and accountability. The weekly meetings create regular opportunities for teachers to engage with the material, receive immediate feedback, and apply their learning in their teaching context, fostering deeper understanding and integration of new strategies.

The structured, multi-week format encourages ongoing reflection and adaptation of practices, enabling teachers to see tangible changes in their performance over time. This sustained engagement is typically more effective than one-time workshops or self-paced learning, as it facilitates continuous learning and a supportive environment for both professional growth and student outcomes.
