Certified teachers with at least one year of teaching experience can be added to our automated substitute finder, AESOP, after interviewing with the Assistant Superintendent for Curriculum and Instruction. Other subs must attend a substitute training class and pass administrative screening before they can be activated in the system. The training class is currently offered in January of each year. Other training sessions will be scheduled as needed. All substitutes are subject to a criminal record check before activation in AESOP.

Midlothian ISD pays $55 per day for substitutes with a high school diploma or GED, $60 per day for substitutes with a four-year college degree, and $70 per day for substitutes with teacher certification from any state. For substitute terms for the same teacher for longer than 10 consecutive days, the pay increases to $90, $100, and $120 for each level of certification. If a substitute is used for a paraprofessional, the rate is $55 per day regardless of the certification level.
