Analysis
NAICS 6117 is the 2022 industry group for educational support services, part of 611 (Educational Services).
It has only one more detailed code, 611710, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 29% and employment rose 33%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
County Business Patterns counts 12,227 US establishments in this code in 2023, employing 141,678 people at an average annual payroll of $61,473 per employee (36th percentile of national industries). 68% of the establishments have fewer than five employees, which marks it as a small-business industry.
By establishments it ranks 3rd of the 7 codes at this level within Educational Services, with 10.4% of them.
