Haynes Academy for Advanced Studies is a Magnet School in the Jefferson Parish School District. Haynes has been designated a Five Star School by the Louisiana Department of Education. The Haynes Academy is named after Vernon C. Haynes, a former principal of the school.

Haynes Academy for Advanced Studies was established in 1909 by the Jefferson Parish School Board and named Metairie Ridge School. By 1912, the wood-framed, one-room schoolhouse had grown to an enrollment of 54. By 1929, grades 1 through 12 had been established and the school was renamed Metairie High School. After East Jefferson High opened in 1955, it was converted to a junior high school and Vernon C. Haynes became the principal.

During the 1968–69 school year, the two-story school building, which had been used for 44 years, was torn down and replaced with the present single-story building. In 1969, it became Metairie Middle School.

On November 22, 1974, the school's name was once again changed to the Vernon C. Haynes Middle School in honor of the former principal.

Haynes Middle School became Haynes Middle School for Advanced People in October 2004, and then became Haynes Academy for Advanced Studies in May 2006 after adding one high school grade each year. The class of 2010 was the first class to graduate from Haynes Academy for Advanced Studies.

In the 2023-2024 school year, the Jefferson Parish School system saw major changes such as the relocation of Haynes Academy for Advanced Studies students to the Grace King High School campus. The current campus is on Grace King Place. There is a proposal to rename Haynes after Grace King as "Haynes Academy for Advanced Studies at Grace King Place.

Though the school's name has changed many times throughout the years, the mascot has stayed the same. The Haynes Academy for Advanced Studies’ mascot is the Yellow Jacket (named Felix and Felicity).

Haynes is a Magnet School that focuses on a particular curriculum set up by the state. Magnet Schools emphasize a particular vocation, such as science, the arts, or mechanics. The admissions process is often very competitive.

The application process occurs in three steps: application submission, the screening phase, and the testing phase. Potential students must first submit a general application online, at any school in the district, or at the Jefferson Parish Public School System offices. Each application will be screened by a panel of three central office administrators. Those who meet the screening criteria will move on to the testing phase of the process. Group paper and pencil tests are administered to potential students. Scores will be reported in the district percentile format and students will be admitted based on those scores.

Haynes offers courses in English, Business, History, Math, PE & ROTC, Science, and Social Studies. Every grade in the school ranks higher in English, Math, Science, and Social Studies than the rest of Jefferson Parish Public Schools and schools in Louisiana in general.
