THE WRITTEN EXAMINATION IS BASED UPON DIVERSE TRADE OR TECHNICAL EXPERIENCE IN THE SPECIFIC APPROVAL AREA BEING TESTED. 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.
THE FOLLOWING LIST OF REFERENCE MATERIALS WAS DEVELOPED AS A GUIDE
FOR WRITTEN EXAM CANDIDATES:
MACHINERY'S HANDBOOK
Industrial Press
TECHNOLOGY OF MACHINE TOOLS by Krar, Oswald and St. Armand
McGraw-Hill
ADVANCED BLUEPRINT READING FOR MACHINE TRADES
Delmar Publishers, Inc.
FAMILIAR PROBLEMS IN MECHANICAL DRAWING by French and Svenson
McGraw-Hill
YOU MAY WANT TO CHECK WITH YOUR LOCAL LIBRARY FOR OBTAINING THESE RESOURCES THROUGH THE INTERLIBRARY LOAN PROGRAM.
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.
