Systematic Review and Meta-Analysis of Token Economy Practices in K-5 Educational Settings, 2000 to 2019.

Kaiser et al. (2022) looked at every K-5 token-economy paper published from 2000 to 2019. They found 24 studies and ran a meta-analysis to see how big the effects really are. The kids were in both general-ed and special-ed classrooms, with and without diagnoses.

Token economies produced a large jump in student performance in every grade K-5. Special-ed teachers used smaller backup reinforcers and faster exchange rates. General-ed teachers used bigger prizes and longer waits. Both ways worked, but the details differed.

The review updates the 1972 warning from E et al. that gains vanish when tokens stop. Young shows tokens still work fifty years later, but Regnier et al. (2022) adds the fix: pair thinning with social praise or self-monitoring to keep the gains.

Gutierrez et al. (2020) is inside Young’s numbers. That study proves you can train staff with just a manual; Young’s meta says once staff run the system, kids learn more.

Azrin et al. (1969) would have landed in the review if it were twenty years younger. Their single-class finding—tokens beat praise alone—matches the large effect Young reports across dozens of rooms.

You can trust a token economy in any elementary classroom. Choose tiny, quick swaps in self-contained rooms and bigger, slower swaps in general ed. Build maintenance from day one: thin the schedule and move control to praise or student self-tracking so the gains survive after the store closes.
