California's Local Control Funding Formula (LCFF) allocates funds to public schools based on demographics, including low-income, English language learners, foster youth, and students deemed at risk. One of the priorities outlined in the Local Control Accountability Plan (LCAP), a planning guide required by school districts and county superintendents, is to increase parental involvement by seeking input from parents in decision-making and promoting stakeholder participation. The purpose of this qualitative case study was to examine the perceived challenges and experiences that administrators of alternative high schools encountered when increasing the parental involvement of low-income single mothers. The study also investigated the perceived challenges and experiences of low-income single mothers regarding parental involvement. The study included 12 participants (five single mothers and seven administrators) from 3 alternative high schools in California. The research found a disconnect regarding the LCFF and the three districts' LCAP definitions of parental involvement held by administrators and the single mothers. Additional findings included challenges related to poverty and being a single mother, and experiences that were primarily negative and related to student discipline. Recommendations include introducing the LCAP policy during the mandatory parent orientation, ensuring the readability of all communication, guaranteeing teachers and students are included in the process, and including the voice of low-income single mothers in creating policy. Future research should investigate students of low-income single mothers, fathers, and/or other caregivers to determine if they should be included as a high needs population in state and local policy.
