#1 to #25 are shown in full above. Here are #26 to #50, in RP Score order; each links to its profile. We publish the top 50 of 93 ranked ABA therapy providers here; the rest are on their profiles.
20 more ABA therapy providers within 40 mi that we can't rank yet: too few reviews, or a specialty we couldn't confirm. Listed A to Z.
We scored 93 Frederick ABA therapy providers on eight factors, weighted as shown. A practice is ranked when its specialty is confirmed and it has 3 or more Google reviews or a claimed profile. A practice with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed November 9, 2026.
Paid placement never changes a rank or score. Sponsored businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
