What's actually in it

Lessons that stay current

All 19 modules, written from a working farm's point of view and updated as California rules and markets shift. Your access includes every update.

The paperwork, decoded

Permit paths, leases, licenses, insurance, labor, and food safety, laid out agency by agency, in the order they actually happen.

Numbers you can reuse

Budgets, cash flow, pricing, and feasibility modeling, including enterprise budgets built from rates measured on a working California seaweed farm. Full Send and above hand you the editable spreadsheets, and the budget labs run the same math in your browser at any level.

Accountability and a record

Checkpoint exams at 80% to pass, major writing assignments read by Jules within a week, and a completion record when it all clears.

Your hours, counted and kept

This course is 19 modules and 51 hours of real, counted class time. In the continuing education world, ten hours of class time is called one CEU, so this course works out to 5.1 CEU. Your hours, quiz scores, and finished work are all kept in a permanent record, and your certificate has a code anyone can use to check that it is real.

The course is built to match a well known national standard for continuing education, called the ANSI/IACET Standard. We have not applied for accreditation yet, and we plan to in 2027. Until that is official, your certificate stands on its own: proof of real hours and real work that an employer or agency can check for themselves.

One note: the counted hours and CEU come with the certificate tiers (Brackish, Full Send, and Faculty Pass). Tidepool is learn-at-your-own-pace, with no reviewed work and no certificate. Read the full academic policies →
