The Robin Hood plan was a media nickname given to legislation enacted by the U.S. state of Texas in 1993 to provide court-mandated equitable school financing for all school districts in the state, in response to the Texas Supreme Court's ruling in Edgewood Independent School District v. Kirby. The law "recaptured" property tax revenue from property-wealthy school districts and distributed those in property-poor districts, in an effort to equalize the financing of all school districts throughout Texas. Background Article 7 of the Texas Constitution states, in part, "it shall be the duty of the Legislature of the State to establish and make suitable provision for the support and maintenance of an efficient system of public free schools". However, the state of Texas only dedicates $.0025 portion of the state sales tax and the net proceeds from the Texas Lottery, as well as earnings from the Permanent School Fund, to primary and secondary education. Otherwise, state funding is determined by the Texas Legislature. The primary source of education funding in Texas remains with the school districts' ability to assess property taxes.

The plaintiffs charged that the state's methods of funding public schools violated the Texas state constitution, which required the state to provide an efficient public school system. School finance lawsuits must take place in state court, since the U.S. Supreme Court ruled in 1973 that education is not a fundamental right protected by the U.S. Constitution (San Antonio v. Rodriguez). The case, Edgewood Independent School District v. Kirby, eventually went to the Texas Supreme Court, which unanimously sided with Edgewood. Passage Passage came in 1993, after the Texas Supreme Court threw out two attempts by the Texas Legislature to write a constitutional school-finance system. The Legislature finally passed a funding plan that was accepted by the Court, in 1993. The goal of the system was an attempt to prohibit wealthy districts from being able to raise revenue to provide benefits which poorer districts could not. Two provisions of the legislation would seek to implement this: First, school districts were strictly limited to a $1.50 tax rate per $100 assessed property value for maintenance and operations (M&O).
