About this chart
- TEA
- Texas Education Agency. Its October count (PEIMS) is the official enrollment number; the 26‑27 point is the district's own snapshot.
- Masked
- TEA hides very small counts to protect student privacy. Where a line depends on one, it is broken and shaded, never drawn as zero.
- Zonda
- The district's demographer. Dashed lines with open dots are its forecast, not counts.
- EC, PK, KG, AD
- Early childhood, pre-kindergarten, kindergarten, adult.
- CHS9
- The ninth-grade campus, combined with Coppell High School by default so lines are comparable.
- Indexed
- Each line is divided by its first value and multiplied by 100, so lines of different sizes can be compared.

About this table
- How to use
- Select a cell to isolate that campus and grade in the trend chart and cohorts; select a campus name to focus it everywhere. On a phone, scroll each table sideways.
- Colour
- Each level has its own shade scale, shown under its table, so colours compare campuses within a level, not across levels.
- EC, PK, KG, AD
- Early childhood, pre-kindergarten, kindergarten, adult.
- Dash (—)
- TEA hid this small number for privacy. It is not zero. In the Total column it means TEA hid the whole campus total, so no change is computed.
- Include EC / PK
- Off removes early childhood and pre-K from the elementary table, its totals and the district line.
- District row
- TEA's official district figure; it can sit a few students above the campus rows.
Cohorts and grade progression

About cohorts
- Class
- Students who entered kindergarten in the same year, followed grade by grade.
- Class size change
- How a class’s size changes from one year to the next as it moves up a grade. Above zero the class gained students (move-ins, transfers in); below zero it lost students.

About the map
- Year
- The map follows the filter-bar year; selecting an event switches it to that event’s year.
- How to use
- Click a dot or zone to select a campus; it is highlighted across the page. The campus list under the table icon is the keyboard alternative.
- Zones
- Attendance boundaries for the school year shown. 23‑24 boundaries were not published, so that year shows 24‑25.
- Zone shade
- Five classes from light to dark maroon, each holding the same number of zones.
- Dots
- Size is enrollment; colour is the change from the prior year (orange fewer, blue more). A dashed ring is a closed campus or one whose exact location is not published; a white dot has no count.
- Capacity use
- Enrolled students divided by stated building capacity.
- Net transfer balance
- Students enrolled at a campus minus students living in its zone.
Impact events, 23‑24 to now
About impact events
- Events
- Board decisions and district changes found in public board materials, grouped by the school year they took effect.
- Before and after
- Switches the map between the year before the change and the year it took effect.
- Attendance change
- Enrollment before and after, from TEA's official counts. It shows what changed around the event, not what the event caused: growth, other boundary changes and open enrollment also move these numbers.
- Arrows
- Width is proportional to the number of students moved, where the board materials give a number.

About this map
- What it shows
- A Census estimate of where school-age children live, not where Coppell ISD students live. It counts private-school, charter and home-schooled children too.
- Survey estimate
- Block-group figures are the Census Bureau’s American Community Survey estimates from small samples; the site shows the Bureau’s published estimate (its margin of error is not shown and is often large). Zone figures are sums of area-weighted block groups (see Estimates on Data & sources).
- Modeled
- The Census publishes public-school enrollment by tract, not block group, so block-group public K-12 counts are modeled from the tract.
- Zonda
- The district’s demographer reviews students by planning area, but those counts are not public. They are available through a public information request.
- Privacy
- No student addresses are used or shown. Everything here is aggregate.
- Zones view
- Expected enrollment spreads the campuses’ combined 26‑27 enrollment by each zone’s share of Census children. Above expected means the campus draws more students than its neighborhood’s share suggests. It is an estimate; for the elementary and middle-school zones, the CISD residence report (25‑26) count of students living in the zone is shown beside it.
- Children 5–17 (Census)
- Residents aged 5 to 17, ACS 2020–2024 five-year estimate, any school.
- Public K-12 (modeled)
- Children in public school, modeled from the tract count by each block group’s share of the tract’s children.
