THE WRITTEN EXAMINATION IS ALIGNED WITH THE MATCHING MASSACHUSETTS VOCATIONAL TECHNICAL EDUCATOR FRAMEWORKS. SOME QUESTIONS REQUIRE A SYNTHESIS OF KNOWLEDGE BASED ON VOCATIONAL TECHNICAL WORK 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.
*You may refer to www.mccte.org for the Massachusetts Vocational Technical Educator Frameworks.

The written exam consists of 100 multiple choice questions. Each question consists of one incomplete sentence or a questions followed by four choices. Listed below are several sample items:
Assume diode (D3) burns out (becomes open), what symptom will be observed at the output?
a. output voltage will equal zero volts
* b. excessive unregulated output voltage
c. fuse F1 will overheat and blow
d. output voltage is not affected
For the circuit below calculate the AC voltage gain of the amplifier. (Assume rE = 5 ohms)
a. 10
b. 50
c. 100
* d. 200
* indicates correct answer
THE TEACHER TESTING PROGRAM WILL PROVIDE NON-PROGRAMMABLE CALCULATORS FOR USE IN COMPLETING THE WRITTEN EXAM. DOCUMENTATION REGARDING THESE CALCULATORS WILL BE INCLUDED IN YOUR ADMISSION PACKAGE.
