Lake Pontchartrain Elementary School
It was originally named the Glade School. The initial facility first began operations in 1989 and had a cost of $6 million. Of all of the school district's schools, it had the highest number of students at the time, which exceeded 1,300. In 2005 the school received its next name and had changes in its mascot and school colors. In 2012 Hurricane Isaac damaged the facility. The planned replacement facility is a smaller size than the previous one. In 2014 the estimated cost of the next facility was $22,500,000, and the projected opening year was 2017. Yeates & Yeates Architects was chosen as the architectural firm.
LaPlace Elementary School
Emily C. Watkins Elementary School - groundbreaking in 2007
It opened in 2009. It was originally supposed to open in 2008, but its opening was delayed. By 2011, the school had perennial issues with its HVAC system. In that period, the school had to have colder than planned temperatures to avoid mold and mildew issues.

It had a fire in 2015, and its replacement facility opened in 2018. In 2025 East St. John Preparatory School is to be renamed Fifth Ward Preparatory School, as the former Fifth Ward Elementary School will close that year.

Historically the institution was a segregated school for African-American students. Previously the facility was a junior high school. In 2024, most of the students were African-American. It is adjacent to a chemical plant owned by Denka Performance Elastomer. It is scheduled to close in 2025, and East St. John Preparatory School in turn is to be renamed Fifth Ward Preparatory School.
