Abbott districts are school districts in New Jersey that are provided remedies to ensure that their students receive public education in accordance with New Jersey’s state constitution. They were created in 1985 as a result of the first ruling of Abbott v. Burke, a case filed by the Education Law Center. The ruling asserted that public primary and secondary education in poor communities throughout the state was unconstitutionally substandard. There are 31 "Abbott districts" in the state, which are now referred to as "SDA Districts" based on the requirement for the state to cover all costs for school building and renovation projects in these districts under the supervision of the New Jersey Schools Development Authority.
Prior to 2011, the State of NJ did not release the total amount spent per pupil on schooling. Since the Abbott original ruling in 1985, New Jersey increased spending such that Abbott district students received 22% more per pupil (at $20,859) vs. non-Abbott districts (at $17,051) in 2011. 
One evaluation concluded that the effect was greater in lower grades and declined in subsequent grades, until there was no effect in high school. The achievement gap in math test scores for fourth graders narrowed from 31 points in 1999 to 19 points in 2007, and on reading tests from 22 points in 2001 to 15 points in 2007. The gap in eighth grade math narrowed less, from 30 points in 2000 to 26 points in 2008, and did not change in reading. The gap did not narrow in high school.
Abbott districts are school districts in New Jersey covered by a series of New Jersey Supreme Court rulings, begun in 1985, that found that the education provided to school children in poor communities was inadequate and unconstitutional and mandated that state funding for these districts be equal to that spent in the wealthiest districts in the state.
The Court in Abbott II and in subsequent rulings, ordered the State to assure that these children receive an adequate education through implementation of certain reforms, including standards-based education supported by parity funding. It include various supplemental programs and school facilities improvements, including to Head Start and early education programs. The Head Start and NAACP were represented by Maxim Thorne as amici curiae in the case.
The part of the New Jersey Constitution that is the basis of the Abbott decisions requires that:
[t]he Legislature shall provide for the maintenance and support of a thorough and efficient system of free public schools for the instruction of all the children in the State between the ages of five and eighteen years.
In 2009, the New Jersey Supreme Court issued its latest Abbott ruling, holding that the State satisfied its constitutional burden by passing the New Jersey School Funding Reform Act of 2008 (SFRA). The Court released the State from prior remedial orders.
Two years later the Education Law Center, the original litigants in the case, challenged that school funding in the state's 2012 budget violated the 2009 agreement. The state's Supreme Court agreed and ruled that the state had to provide an additional $500 million to the state's 31 Abbott districts. 
There is, however, limited evidence that the legal actions have improved student learning outcomes in the Abbott districts.
The Court in the Abbott II ruling of 1990 explicitly limited the Abbott programs and reforms to a class of school districts identified as "poorer urban districts" or "special needs districts." In 1997, these districts became known as "Abbott districts." The Court identified the specific factors used to designate districts as "Abbott districts." These districts:
- must be those with the lowest socio-economic status, thus assigned to the lowest categories on the New Jersey Department of Education's District Factor Groups (DFG) scale;
- "evidence of substantive failure of thorough and efficient education;" including "failure to achieve what the DOE considers passing levels of performance on the High School Proficiency Assessment (HSPA);"
- have a large percentage of disadvantaged students who need "an education beyond the norm;"
- existence of an "excessive tax [for] municipal services" in the locality where the district is located.
Using these factors, the Court in Abbott II identified 28 districts as Abbott districts. The Court also gave the New Jersey Legislature or the Commissioner of Education the authority to classify additional districts as Abbott districts based on these factors, which would then entitle the children to the Abbott programs and reforms. In 1998, the Legislature classified 3 additional districts, bringing the 2009 total of Abbott districts to 31.
The program improved achievement in early grades, but not in upper grades. Early education programs including free preschool helped close part of the gaps for Fourth graders whose performance gap "narrowed from 31 points in 1999 to 19 points in 2007, and on state reading tests from 22 points in 2001 to 15 points in 2007." However, as students advanced in grade, their relative performance gains were lost, such that high school students showed no improvement at all and one expert, the Assistant Commissioner at the New Jersey Department of Education from 2002 to 2007 said that the program had not eliminated the effects of poverty. "When you get to middle school, eighth grade, high school – forget about it. This has been a huge failure."
In 2008, a Fairleigh Dickinson University PublicMind poll surveyed New Jersey residents about their awareness of and attitudes towards the Abbott decisions; 57% of voters reported that they had heard or read “nothing at all” about the Abbott decisions. Only 12% of voters responded that they had read or heard “a great deal” about the Abbott decisions. The survey also found that, despite a seeming lack of knowledge about the Abbott decisions, voters in New Jersey largely approved of the court decisions with 55% of the public approving and 28% disapproving. Dr. Peter Woolley, Executive Director of the PublicMind Poll, explained the results by stating, “voters don’t know the details but they agree with the principles.”

They were formerly known as Abbott Districts, based on the Abbott v. Burke case in which the New Jersey Supreme Court ruled that the State must provide 100 percent funding for all school renovation and construction projects in special-needs school districts.... The districts were renamed after the elimination of the Abbott designation through passage of the state’s new School Funding Formula in January 2008."
