Students must also demonstrate 100% competence of 25 basic configuration clocks in accordance with criteria specified on a standardized performance evaluation form. Failure to pass the written or motor-skill pre-entrance tests will automatically result in the trainee’s dismissal from the course. Performance of 100% proficiency is required in all motor-skill testing areas. Upon course completion, students must attain a minimum of 75% on a written exam administered by commission staff prior to being certified as a Time-Distance Instructor. There will be an assortment of motor-skills testing throughout the training course for which the student must successfully complete before graduation from the training is permitted.
