What is The PDI School?
A development community for PDIs and ADIs who want more than just passing tests: weekly live sessions, structured frameworks, and a community built around real lesson development.
Is it only for trainees still on Part 1–3?
No. Whatever stage you're at, training or already qualified and wanting to get better, you're welcome.
What does the free trial include?
Your free trial gives you the opportunity to experience The PDI School before deciding whether it's right for you. During your trial you'll receive: access to the initial phase of our recorded development content; access to any live community Zoom sessions taking place during your trial; access to a selection of our AI applications; full access to the community, discussions and member support; and access to debrief notes from previous live sessions, so you can learn from past discussions even if you couldn't attend.
