“I gained a lot of experience simply by writing the prac report. I gained a whole bunch of experience just taking your class, but this report helps me because we have never done a report like this at our agency, so it’s a good starting point for change.”
Ben, Des Moines Police Department

“Great practical sessions, very beneficial to be able to examine swatches under the microscope and create our own patterns for examination.”
Jennifer, Alberta
