Calvert County Public Schools uses KeepnTrack for visitors and volunteers sign in and sign out. Since July 1, 2010, all visitors and volunteers are screened each time they enter a school or facility. All volunteers will need to complete an Online Volunteer Application before they may begin service as a volunteer in any school or schools. If completing an application online is not possible, paper applications are available in all schools. Applications must be submitted after the prospective volunteer has completed all parts of the application process. A signature will be required on all paper applications and the applicant will need to sign an Attestation Letter that he or she has read Calvert County Public Schools: Volunteering in Our Schools.
