earnable

Capable of being earned.

Something that can be earned, especially a reward for good behavior.

In the past, I have had the most success with "earnables," which involve structured free time and normally scheduled activities (e.g., working on a special project. A teacher should avoid buying the child out with edibles and material rewards (which soon lose their effectiveness or become too costly), and establish a firm time period(s) for reinforcement delivery that is not too distant from the work period ( i.e., avoid home-based or after-school consequences when possible — these children are impulsive and have inadequate delay skills!) .

What Ferdinand would hoard, she circulates. He fastens on the absolutes of ascriptive identity; the duchess, on the earnables of achieved character.
