So we filled them.

Free STEAM classes, taught by student volunteers.
No cost. No experience needed.

Someone like you is teaching.

Our teachers are students. They learned it, then they taught it. That's the whole model.

Everything you give comes back counted.

Teaching and volunteering hours are recorded in the app, then reviewed by a person — not by a counter on a page. Here is the whole process.

Step one
You log the hours you actually worked — the date, the class, what you did.
Step two
Your chapter lead reviews the entry and approves it, or asks you about it first.
Step three
At the end of a run, the library signs off on the approved totals for that chapter.

Students can become teachers.

Any student who takes a class here can apply to teach one. The invitation is open to every learner who wants it.
