Mission
The mission of the school is to provide a quality, well-rounded education to the students, and to challenge each student to strive to perform to the best of his or her ability. In doing this, the school works to provide an environment characterized by high moral standards, the latest technology, and a skilled, knowledgeable staff to guide students.
As stated on its FY2025 Form 990.
Programs
The organization provides education to students in the form of classroom instruction and labs geared towards equipping students with the necessary background to continue with post-secondary education after high school graduation. Classroom instruction is provided following a normal school day consisting of seven class periods. The school year falls within the normal pattern followed by schools within the region, beginning in August, and ending in May. School begins at 800am and ends at 310pm. The curriculum provided follows the required courses of instruction as set forth by the State of Louisiana, Department of Education. Additional honors courses are offered, as well. The school provides opportunities for upperclassmen to obtain college credit by offering dual-enrollment classes in english and mathematics. As part of providing a well-rounded education, the school offers sports programs, such as football, basketball, baseball, softball, track, golf and tennis. Cheerleading and dance team activities are also offered.

The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $2.9M to $4.4M (+51%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2019 0% · 2020 0% · 2021 10%. Grants only. Government contracts and fees sit inside program revenue.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
