Methodology

Top 10 rankings

Our Top 10 lists are ranked algorithmically by quality score — a cohort percentile ([0, 1]) that combines six signals:

• Parent-appeal judgment (45%) — an Opus-authored 1–5 rating with cited evidence from the camp's website, reviews, news, and licensing records.
• External rating signal (20%) — Google Places or Yelp star rating × review-count volume, normalized within the category cohort.
• Operating tenure (20%) — years in operation, capped at 15.
• Accreditations and licensing (5%) — ACA accreditation, state/provincial childcare licenses.
• Catalog completeness (5%) — how many data fields the camp has filled in, as a rough proxy for operator attentiveness.
• External review volume (5%) — how many parents have left ratings versus the cohort.

A camp with a credible safety concern — active state-license revocation, BBB F-rating, or credible incident reports — is excluded entirely. Safety is a gate, not a weight.

What we don't rank on

We do not accept paid placement, affiliate arrangements, or inclusion fees. No camp can buy a slot on any Top 10 list. Editors retain the right to make small manual adjustments — typically to correct individual misjudgments by the automated pipeline. When that happens, the adjustment and its reason are stored in the catalog and visible on the article itself.

Freshness

The list is read live from our catalog at request time and always reflects current scores. The prose commentary regenerates only when the Top 10 composition materially changes (top-3 reshuffle or three or more slot changes out of 10). Both clocks are shown on each article — "Prose last updated" and "List last verified."

What we rank

Only US and Canadian day camps and specialty camps in our active catalog. Virtual-only programs, travel camps, and overnight camps (tracked separately) are excluded from the Top 10 lists for now. Cells with fewer than 20 externally-rated camps, or whose tenth- ranked camp scores below the 60th percentile, are not published — thin rankings would be misleading.

Catalog and coverage

The catalog covers 19,500+ active camps across the United States and Canada. Coverage is deepest in the top 30 metros; smaller metros have partial coverage and fewer ranked camps. We refresh external ratings on a rolling six-month cadence per camp.
