How Felicitas Mendez Intl School compares with Oklahoma and U.S. medians
Larger classes than state median
20.6:1 - 4.5 above the Oklahoma state median of 16.1:1, indicating larger average class loads than typical schools in the state.
Felicitas Mendez Intl School's enrollment sits away from the most extreme size bands, but its reported student-teacher ratio is heavier than most Oklahoma schools. That isolates staffing load as a more useful concern than raw campus size. A high ratio does not establish weak teaching or outcomes, yet it can indicate less adult capacity per enrolled student. The remaining federal indicators show whether support staffing and program access offset that pressure.
Felicitas Mendez Intl School serves a combined grade span rather than a conventional elementary, middle, or high-school band. That structure can require the same campus to cover transitions, counseling needs, and programs for students at substantially different developmental stages, so a single staffing ratio deserves more caution than it would at a narrower-grade school. Federal totals show the available people and programs, but not how those resources are divided among grade levels.
