The problem
Teaching candidates in California write long, structured responses for the CalTPA. The work is split into parts with specific requirements, and a candidate needs to see whether a draft addresses the rubric's categories before submitting it.
From blank page to checked draft
What it does
- Templates for Parts A, B, C, G, and H.
- A searchable library of the relevant standards.
- Keyword highlighting and a radar chart of how well a draft covers each keyword category.
- A 14-page guide to the credential pathway.
How it is built
Two Cloudflare Workers and a D1 database with prefixed tables. Accounts use PBKDF2 password hashing and HMAC-signed sessions, and new accounts wait in an approval queue. The public demo runs without an account and keeps drafts in the browser.
Scope & limitations
The public demo stores drafts only in the browser. It does not guarantee a score or a credential.
