Document and Verify your experience (if required)

Full and Part-Time Work Experience Defined

Full-time experience is defined as a minimum of thirty-five (35) hours per week. Individuals who have part-time experience may be permitted to utilize prorated part-time experience to meet the work experience requirements.

For example, if you are employed 20 hours per week for one year, your experience would be computed as 20 divided by 35 multiplied by 52 weeks, or the equivalent of 29.7 weeks of full time employment.

Please contact the ASCP Board of Certification office prior to applying, if you have any questions concerning part-time experience.

If the number of years of experience required must be completed within the time frame, specified in the requirements, calculated from the date of application (e.g. application submitted 3/1/07; experience acceptable from 3/97 for at ten-year time frame). Simultaneous experience at two different places of employment in excess of 35 hours per week is not counted toward the experience requirement.
