Can school accommodation letters be reused for workplace accommodations later?

Often, yes. Documentation from school can still be useful, especially if it outlines diagnosis, functional impacts, and effective supports. That said, workplaces usually focus less on diagnosis and more on how symptoms affect job performance. Older letters may need a brief update to reflect current functioning and job demands. Clinicians often reuse the core assessment and adapt the language to the workplace context. The goal isn’t to start from scratch but to translate existing evidence into a new environment.
