The state of Massachusetts requires that all trainees take 45 hours of primary education.
This includes:
1) A 30-hour course (An introductory course to real estate appraising is recommended)
2) A 15-hour Uniform Standards of Professional Appraisal Practice Course
Both the Basics and the Uniform Standards courses will fulfill the 45-hour Massachusetts
requirement. Once successfully completed, you may then apply to the state of Massachusetts for a trainee license.
See the Massachusetts board link to the trainee application.
With that trainee license you must then work under a licensed/certified appraiser for
a minimum amount of 2 years and acquire 2000 work experience hours.
