* Property Taxes: This is the largest source of funding for McKinney ISD. Property owners within the McKinney ISD boundaries pay property taxes, and the revenue generated is a significant portion of the district's budget.
* State Funding: The Texas state government provides funding to school districts based on various factors, including student enrollment and average daily attendance. The formula for this funding is complex and can change from year to year.
* Federal Funding: The federal government provides funding for specific programs and initiatives, such as special education, Title I programs (for disadvantaged students), and programs aimed at improving school infrastructure. This funding is generally less than state or local funding.
* Other Revenue Sources: These can include things like bond elections (for capital improvements like building new schools or renovating existing ones), grants from various organizations, and sometimes, smaller sources like fundraising activities.
It's important to note that the specific proportions of funding from each source can vary from year to year depending on state budgets, property values within the district, and federal funding allocations. The McKinney ISD website is the best place to find the most current and detailed breakdown of their funding sources.
