20 public K-12 schools in Port Arthur from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
According to NCES CCD 2024-25, Port Arthur has more public-school enrollment than 82% of the 4,487 US cities in this directory. Port Arthur sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
Combined-grade campuses shape the local portfolio
11 of Port Arthur's 20 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
Economic need crosses separate district systems
84.5% of enrollment in reporting Port Arthur schools is eligible for free lunch, while the city list spans 4 districts. That pairing makes a citywide average especially easy to misread: the need measure follows students, but staffing decisions, calendars, program rules, and federal allocations are administered through separate district structures. The 33-point gap between Memorial H S and Staff Sergeant Lucian Adams El shows how much reported resource capacity can vary inside the same municipal label. Compare schools within the same district first, then use the city view to see how those local systems differ.

Memorial H S accounts for 20.2% of all Port Arthur public-school enrollment
That concentration means Port Arthur-wide averages can mask substantial variation outside the largest entity. Grade level: High. The share measures enrollment concentration only; it does not establish how districts allocate programs, capital, or staff. Enrollment-weighted aggregates give this entity more weight than any smaller peer, while an unweighted entity average treats every record equally.
Port Arthur school enrollment varies 47× across entities
Port Arthur school enrollment ranges from 46 students (lowest) to 2,140 students (highest), a spread of 2,094 students. That ratio is among the widest observed and reflects extreme heterogeneity inside a single city, with small specialty programs listed alongside large comprehensive campuses. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.
The reported share is at least 75%, indicating a high concentration of measured economic need. Title I operates under the Every Student Succeeds Act (ESSA, 2015), but its statutory allocation uses additional LEA-level counts and rules not represented by this average. This percentage is an economic-need context measure; it does not establish a Title I award, show dollars received, or describe how funds are distributed among campuses.
Port Arthur student-teacher ratio is 14.3:1 — near the typical range (US average ~15.7) — citywide staffing is neither unusually lean nor unusually crowded by this measure
student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Variation between sub-units within Port Arthur is typically wider than the Port Arthur-aggregate figure suggests.
30% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.
