I recently took the Pre-Course assessment. I passed the Safety assessment but when I finished the DIAD overview and DIAD parts 1 and 2. There was no assessment test but according to the packet I received, there is an assessment test for DIAD. After completing the DIAD portion the whole pre-course disappeared from my UPS University page. Was that suppose to happen when you completed the pre-course? Is there an assessment test for the DIAD portion?
