THE WRITTEN
EXAMINATION IS ALIGNED WITH THE MATCHING MASSACHUSETTS VOCATIONAL TECHNICAL
EDUCATOR FRAMEWORKS. SOME QUESTIONS
REQUIRE A SYNTHESIS OF KNOWLEDGE BASED ON THIS EXPERIENCE AND MAY NOT BE FOUND
IN ANY BOOK. HOWEVER, CANDIDATES ARE
ENCOURAGED TO STUDY FOR THEIR EXAMS BY REVIEWING CURRENT TEXTBOOKS AND
REFERENCE MATERIAL WHICH CAN USUALLY BE FOUND IN THE LIBRARIES OF MOST
VOCATIONAL TECHNICAL SCHOOLS AND SCHOOLS WHICH OFFER CHAPTER 74 PROGRAMS.
