AISD Service Center. AISD has not standardized its custodial shifts and responsibilities. Although AISD housekeeping specialists make recommendations to improve the quality and efficiency of district custodial services, school principals, who manage custodians on campuses, are not obligated to follow them.
Principals determine custodial shifts, assignments and responsibilities for their schools.
Exhibit 5-36 shows AISD's housekeeping allocation calculations by school level. The housekeeping allocations by shift are recommendations provided by the department of Housekeeping Services to district schools. According to these recommendations, approximately 32 percent of high school custodians and 39 percent of middle school custodians should be working during the day shift. However, the actual distribution of custodians varies by school and changes frequently. Moreover, school opening and closing hours are determined by school principals.
