Walter S. Smith, the co-author of EPA Reference Methods 1-8, will lead the instruction of this hands-on workshop. The object of this 5-day seminar is to prepare the student for the Source Evaluation Society's Qualified Source Testing Individual (QSTI) Exam I through and IV. This workshop is very intense. The workshop concentrates on the written method details but not necessarily the "why" they are written that way (although some of the "why" will be discussed). The purpose of the SES Exams is to find out if you know the methods in details. The workshop will center on how to find the answers in the CFR (and in the process, hopefully, you will learn the details). The QSTI Exams are open book with some tricky questions, so the details are important. The workshop devotes about 1/4 of the time on each exam. If you are interested in becoming a QSTI from SES, you must, at least, pass the exam for the group of methods that you oversee on site.
See Course Agenda

The prerequisite for this Workshop is to have read all the EPA methods of the group of interest in the CFR. No manual is given for this workshop since the CFR is your manual. However, a comprehensive methods book will be given to the students that include the methods in the four groups however, you may bring your own Parts 51 Appendix M, 60 Appendix A, B & F, 61 Appendix B, and Part 75 Appendix A (and the ASTM D6784-02 if taking Exam 4), page tabs and a two colors of Highlighter. Note: the methods book will not include ASTM D6784-02.) If you are going to take the exams (that are given at the end of the workshop), and have read the methods in the CFR thoroughly, this workshop will improve your score. The pass fail rate without the workshop is about 50%.

At the completion of the workshop, Exams I, II, III and IV of the Source Evaluation Society's Qualified Source Testing Individual Exams will be administrated by ETA.


Participants will receive comprehensive quizzes and other preparations for the exams. The cost of the Preparation for the SES QSTI Exams Workshop is $1,199us. This amount covers the tuition; it does not include hotel accommodations, meals or the cost of the SES examinations. At the completion of the workshop, Exams I through IV of the Source Evaluation Society's Qualified Source Testing Individual will be administrated by ETA. The costs of the SES exams are separate.
