SAUDI ARAMCO API INSPECTOR TRAINING PROGRAM 2.0 – Inspector Preparation and Training (Course Overview) In the new training program currently being initiated at Saudi Aramco, API course Participants cover training items and are shown how to acquire the following skills to prepare for API exams:        

Perform & Practice all critical calculations relative to Examination Body of Knowledge Apply Code requirements to questions and calculations that appeared on previous exams Understand Codes and important points most likely to be covered on API examinations Understand Welding Procedure Specification basics and Welding Code Requirements Review all Examination effective publications and highlight items per Examination rules Understand the applicable Damage Mechanisms per API 571 associated with exams Prepare API Examination Publications (highlight, tab, index) for quick & easy reference Tips for Time Management and managing stress associated with Professional Exams

3.0 – Inspector Commitment to Self-Study (Read Carefully Before Signing) API examinations are difficult for those who are unprepared to take on the added responsibility for self-study. There is no “magic formula” or any training course or seminar that can prepare you 100% for these exams. In the past, overall Pass/Fail rates on API exams have been very poor for Saudi Aramco employees because of a lack of proper preparation for the Professional exams. These failures have been carefully analyzed and a careful and considerate course preparation has been developed that includes two weeks of training for each of the three major API certifications. API course Participants are requested to make a commitment to self-study prior to participating in their applicable API Training Course. If you are unable to commit to the additional self-study hours recommended, it is recommended that you discuss this with instructor or not participate in the Classroom Training. If you have significant self-study time already, see Sect. 4, Instruction 2. Your name & signature below states that you are serious and committed toward achievement of your requirements for preparation for your Professional exam and that you will follow the Saudi Aramco API Training Program guidelines and perform / document self-study after completion of your Classroom training.
