I only give, I don't know, about 10% or 20% for getting the right number in a computation. I tell my graders, if the student demonstrates minimal acceptable proficiency that student has to get a passing score.
Licensing standards vary by state and occupation, but typically require a minimum level of education in a specified field and apassingscore on a test of competence.
In fact, two people with opposite ideas about, say, animal rights, could both get the equivalent of apassingscore from the program, as long as their ideas were internally consistent.
They are less successful motivators if they reward students for reaching a certain level of performance, such as achieving apassingscore on a test, according to research by Roland Fryer.
