Rating category
A rating category is a band of ratings, often 200 points wide, that groups players of similar strength so they can be sectioned, paired, prized and described together in a tournament.
A rating category turns a continuous number into something you can say aloud. Chess rating scales are built around a 200 point step: FIDE's regulations describe the scale as having a class interval of 200 points (Rating Regulations, clause 8.1), and US Chess pegs its rating-based titles to levels 200 points apart, from 4th Category at 1200 through 1st Category at 1800 to Candidate Master at 2000.
FIDE does not hand out classes to ordinary players. Its Title Regulations acknowledge only the titles they list, which are GM, IM, FM and CM and the women's equivalents (clauses 0.1 and 0.3). Organizers and clubs therefore make their own letter or name labels for bands, and a label means whatever the event announcement says it means.
The main practical use is sectioning. A large weekend event often has an open section plus sections capped at a rating, so a 1400 player is not paired against a 2200 player in round one and prizes are competitive inside each band. Prize rules interact with it too: US Chess can set a rating floor when a player wins a large prize in an under-rating section.
Crossing a boundary changes only the label. Read the announcement for the real limits, and see the entries on rating list, open tournament and US Chess rating.
A neighboring idea is Scholastic tournament. A scholastic tournament is an event for school-age players, usually organized in sections by grade or age, with prizes for individual students and often for school teams as well.
Also worth reading is Sectional. A sectional is a tournament section limited to players inside a set rating range, so that each competitor mostly faces opponents of similar strength and prizes are fought for fairly.
Rating and title terms like "Rating category" matter once you know your next step, and the improvement plans by rating band set out a weekly routine for each rating range.
