The requirement for certi- fication for a Technologist GDTP is to successfully pass the Technologist GDTP examination. 2.2.2 Senior GDTP. The requirements for certification for a Senior GDTP are as follows: (a) 5 yr ofdocumented experience in the field ofGD&T intherecognizeduseofthesysteminbothapplicationand understanding. (b) successfully passing the Senior GDTP examination. Anindividual is notrequired to be a certified Technologist GDTP to qualify for taking the Senior GDTP examination. 2.2.3 Equivalencies. NotethatASME Y14.5-2009 is not equivalent to ASME Y14.5M-1994. Successfully passing the ASME Y14.5-2009 examination does not confer certi- fication to ASME Y14.5M-1994. Successfully passing the ASME Y14.5M-1994 examination does not confer certifi- cation to ASME Y14.5-2009. 3 TEST REQUIREMENTS (EXAMINATION) 3.1 Technologist Level Examination The Technologistlevel examination is a maximum of 4 hr in duration, consisting of 150 questions. The exam- ination is a closed-book, multiple-choice, written exami- nation evaluating the applicant’s knowledge of GD&T principles, concepts, and practices in accordance with ASME Y14.5M-1994 or ASME Y14.5-2009. The topics for ASME Y14.5M-1994 certification are defined in Mandatory Appendix A, and those for ASME Y14.5- 2009 certification are defined in Mandatory Appendix C. The approximate distribution ofquestions is as follows: (a) ASME Y14.5M-1994 Examination (1 ) 10% on scope, definitions, and general dimensioning (2) 10% on general tolerancing and related princi- ples, and former practices included in ASME Y14.5M- 1994, Appendix D (3) 5% on symbology (4) 15% on datum referencing (5) 30% on tolerances of location (6) 30% on tolerances of form, profile, orientation, and runout For the ASME Y14.5M-1994 examination, a candidate must achieve an overall grade of at least 75% and score at least 50% in each of the preceding categories. (b) ASME Y14.5-2009 Examination (1) 10% on scope (2) 10% on general dimensioning (3) 5% on symbology (4) 20% on datum referencing (5) 5% on form (6) 5% on orientation (7) 25% on location (8) 15% on profile (9) 5% on runout For the ASME Y14.5-2009 examination, a candidate must achieve an overall grade of at least 78% and score at least 50% in each of the preceding categories. 3.2 Senior Level Examination The Senior level examination is a maximum of 6 hr in duration,consistingof150 questions.Theexaminationisa closed-book, multiple-choice, written examination. The Senior level examination emphasizes knowledge, selec- tion, and application ofthe dimensioning and tolerancing principles, concepts, and practices contained in ASME Y14.5M-1994 or ASME Y14.5-2009, includingappendices. The topics for ASME Y14.5M-1994 certification are defined in Mandatory Appendix B, and those for ASME Y14.5-2009 certification are defined in Mandatory Appendix D. The approximate distribution of questions is as follows: (a) ASME Y14.5M-1994 Examination (1) 10% on topics from the Technologist level body of knowledge (see Mandatory Appendix A) (2) 20% on datum selection (3) 40% on geometric tolerancing and related prin- ciples, tolerance calculation, and ASME Y14.5M-1994 Appendices (4) 15% on application of modifiers in feature control frames (5) 15% on composite tolerancing For the ASME Y14.5M-1994 examination, a candidate must achieve an overall grade of at least 80% and score at least 50% in each of the preceding categories.(b) ASME Y14.5-2009 Examination (1) 10% on scope, general dimensioning, symbology (2) 30% on datum referencing (3) 5% on form (4) 5% on orientation (5) 25% on location (6) 20% on profile (7) 5% on runout For the ASME Y14.5-2009 examination, a candidate must achieve an overall grade of at least 78% and score at least 50% in each of the preceding categories.
