Key metrics for the language schools industry.
Industry Definition & Overview
Language Schools (NAICS 611630) encompasses establishments primarily engaged in offering foreign language instruction, including English as a Second Language (ESL) programs, and sign language instruction per the U.S. Census Bureau[5]. Instruction may be provided through classroom-based courses, private tutoring, immersion programs, corporate language training contracts, and online or hybrid delivery platforms. These schools issue certificates of completion rather than academic degrees.
Roughly 1,053 establishments employ 23,300 workers and generate approximately $1.7 billion in annual revenue per the Bureau of Labor Statistics[6] and Census data. FLS International and Golden Gate Language Schools rank among the larger U.S.-based operators, while technology companies such as Rosetta Stone compete through AI-powered digital platforms. Industry revenue has declined at a negative 2.7 percent annual rate over the past five years as mobile applications and free online platforms eroded traditional classroom enrollment.
Per the SBA Table of Size Standards[7], the size standard is $20.5 million in average annual receipts. The global language learning market stands at roughly $85 billion, with projected growth to $649 billion by 2035 driven by cross-border commerce and immigration. U.S. traditional language instruction has faced structural headwinds from digital alternatives, though corporate demand for cross-cultural communication training and immigrant ESL services continues to provide stable revenue for classroom-based operators. Learner attrition remains high, with roughly 48 percent of students abandoning courses before reaching intermediate proficiency levels.
