Short answer
Not replaced, but changed. BLS rates the exposure as high, so AI can help with a real share of the work, yet it still projects employment to grow.
AI and jobs
The Bureau of Labor Statistics places substitute teachers in its high AI exposure category, above the middle of the pack: a substantial share of the work overlaps with what AI can do. BLS projects employment to change by +2.0% over 2025–2035, against 3.5% for all occupations, with about 65,000 openings a year.

The federal measure
The Bureau of Labor Statistics publishes a relative AI exposure category for each occupation it projects, built from five public measures of where AI could be, or already is, used to assist with or complete the work. Substitute Teachers land in the high category: above the middle of the pack: a substantial share of the work overlaps with what AI can do.

Inside the work
O*NET rates how important each work activity is to an occupation and how often each working condition comes up. The ratings below are the ones that move the job's NueCareer AI-resilience score the most: the ones that pull it up, and the ones that pull it down. Only ratings clearly above the midpoint count.

The jobs
Exposure says where AI meets the work. The BLS projection says what the labor market is expected to do over 2025–2035. BLS projects +2.0% change in employment over the decade, against 3.5% across all occupations, and about 65,000 openings a year once retirements and career changes are counted. About 524,770 people work in the job today, at a median of $41,670 a year (BLS OEWS, May 2025).

Questions
Not replaced, but changed. BLS rates the exposure as high, so AI can help with a real share of the work, yet it still projects employment to grow. BLS defines exposure as AI being able to assist with or complete some of the work, and says it does not imply job loss, productivity gains or wage effects. BLS projects employment to change by +2.0% over 2025–2035, against 3.5% for all occupations, with about 65,000 openings a year.
BLS sorts 786 occupations into four relative categories: low, moderate, high and very high. Substitute Teachers are in the high category, alongside 189 other occupations. The categories combine five public measures of where AI could be or already is used, and they compare occupations with each other rather than giving an absolute risk.
In O*NET's description of the work, the parts that overlap most with what AI handles well are getting information, documenting/recording information and email. The parts that hold up best are assisting and caring for others, face-to-face discussions and resolving conflicts and negotiating with others. These come from O*NET ratings of how important each activity is to the job, read through NueCareer's AI-resilience method.
On NueCareer's AI-resilience score, built from O*NET work activities, substitute teachers score 40 out of 100, higher than 40% of the occupations we score. The job pays a median of $41,670 a year (BLS OEWS, May 2025). No job is fully safe from technological change, but the federal exposure category and the projected openings are the two numbers worth weighing.
Preschool Teacher, Except Special Education (moderate exposure, $38,140 median), Kindergarten Teacher (moderate exposure, $62,680 median). Each is in a lower BLS exposure category than substitute teachers, and most are listed by O*NET as related to the work.
