The contractor, not the district, is responsible for contacting DPS directly to set up an account for the purposes of obtaining criminal history record information.

Any offense against a child 2.

Any sex offense 3. Any felony offense involving controlled substances 4. Any felony offense against property 5. Any other offense the District believes might compromise the safety of student, staff or property. A Bidder/Proposer’s violation of this section shall constitute substantial failure.
