STEM
Mesquite ISD offers STEM classes through its Staff Development Department; you can enroll in classes through Staff Development in the fall and spring. MISD will pay the cost of the class; however, you will not receive "pay for knowledge" money for taking the class since MISD pays the tuition.
Once you start taking the STEM classes, you will want to save your certificates, so you can submit them for STEM certification when you are done with the program, which will earn you a $500 stipend from the district.
