Efficacy and maintenance of an education program for a consumer cooperative.

Researchers set up a credit and fine system in a student-run food co-op.

Members earned credits for finishing study guides and paid small fines for skipping.

They used an ABAB reversal design to test the rules.

The co-op had about 30 college-age members.

When credits and fines were on, study-guide completion jumped five times higher.

When the rules were off, work dropped back to baseline.

Nine years later the students still ran the same system with no staff help.

Kohlenberg et al. (1976) did something similar in a group home. Rent credits for chores boosted work and saved money. The co-op study shows the same credit/fine logic works for school work.

Potter et al. (2013) paid homeless adults cash for attending job training. Payments doubled attendance, just like credits multiplied guide completion. The pattern holds across ages and settings.

Robinson et al. (1974) warned that fines can backfire by excluding people. The co-op avoided this by keeping fines small and letting members earn credits right away.

You can run a credit/fine system with almost no cost. Post the rules, hand out cheap tokens, and watch participation climb. After a few weeks the students may keep it going themselves, freeing you to focus on other goals. Try it in student councils, peer-tutoring rooms, or life-skills classes where members share real work.
