Once the student knows how to do a task, s/he
needs enough practice to make it his/her own and
not forget it.
Practice is repeated until the student performs the task at fluent levels. Fluency is defined as performances within a range of frequencies in a given period of time with a given range of incorrect responses. (e.g. The student reads a story orally at 200-250 words per minute with no more than 2 errors.)
