Summary

Mariner High School in Cape Coral, FL, is a large public high school serving 1,865 students in grades 9-12 within the Lee district, a district ranked in the bottom 20th percentile statewide. The school has shown recent improvement, moving from a 1-star to a 2-star rating, but its overall state ranking (41st percentile) places it in the middle of the pack among Florida high schools.

The most striking feature of Mariner is its "graduation paradox": it boasts an exceptional 94.5% graduation rate, well above the district (89.8%) and state (92.2%) averages, yet academic proficiency on state tests is very low. For example, only 8% of students were proficient in Algebra 1, and 47% in 10th-grade ELA. This suggests the school may be effective at helping students earn diplomas but struggles to ensure they meet rigorous academic standards. A major contributing factor is critically high chronic absenteeism—48.4% of students were chronically absent in 2023-2024, the highest among traditional large high schools in the area and far above the district (34.6%) and state (31.4%) averages. The school also has the lowest spending per student ($9,439) among comparable area schools, which may limit its ability to address these challenges.

Mariner's performance is uneven across subjects. While Biology 1 proficiency reached 77% (above state averages), Algebra 1 proficiency was just 22%—far below the district (56%) and state (63%) averages. This indicates a strong science department but significant math struggles. Encouragingly, ELA scores have shown consistent improvement, with 10th-grade proficiency rising from 35% to 53% over three years. Compared to its closest neighbor, North Nicholas High School (1.78 miles away), Mariner performs significantly better, as North Nicholas has a 52.6% graduation rate and 90% chronic absenteeism. The most similar school in performance is Island Coast High School, which shares similar low Algebra 1 proficiency (21%) and high absenteeism (44.1%), suggesting both schools serve a comparable student demographic facing similar challenges.

Open Quote This school is one of the worst schools my daughter has ever attended. How can they consider it is good schooling to give a child days off for being late for detention. I would like to know the benifit to the child to have time off without learning or being given any work. I think there are too many people with way too much time on their hands, and they're not taking the students best intrest into consideration. They kids go to school for education not to be denied education because they were caught on the phone between classes, wearing a pair of jeans with a rip in the leg, etc. This school might want to take a hard look at what they are really teaching the kids. These kids aren't bad they are kids and need rules but not at the extent that this school has gone. Close Quote
