Charter school search splits by grade band first. "Charter elementary school Phoenix" and "charter high school Phoenix" are different queries with different shortlists, even when one operator runs both. A directory that ranks needs a page per grade band in every metro, with the right schools, enrollment numbers, and state rating.

SleekRank reads a Google Sheet with one row per charter school and renders each through a WordPress base page. A grade_band column drives /charter-schools/{grade_band}/{city}/ and a slug column drives /charter-schools/{slug}/ profile pages. Both page groups share the same sheet, so adding a K-8 school is a column value, not a template fork.

Enrollment, authorizer, state report card grade, and waitlist size map to tag and selector mappings on the base page. When the state department of education publishes its updated report card CSV (most do once a year), you sync the column, clear the SleekRank cache, and every page rebuilds with the new rating without touching individual posts.

Charter school searches behave more like public-school enrollment queries than like private-school queries because parents filter by grade band first and by location second. The grade band is the head term: K-5, 6-8, 9-12, K-8, K-12. Each band has its own enrollment lottery cycle, its own state report card weighting, and its own search intent.

A K-5 charter competes with the local elementary school on test scores and before-after care. A 9-12 charter competes on graduation rate, AP offerings, and college placement. Mixing them on one page hurts both queries.

State report card grades also change once a year on a published schedule, and a directory that surfaces last year's rating without a date stamp is worse than not surfacing it at all because parents make enrollment decisions on freshness. Programmatic generation makes that maintenance loop manageable. One row per school, one cell per rating, one cache flush per sync.

The directory stays current with the state portal, the page-per-grade-band structure matches how Google interprets the queries, and editorial work shifts to the things that actually need judgment, like principal interviews and lottery walkthroughs. SleekRank does not rate schools, but it removes the structural reason charter directory data goes stale.
