  This exam study guide is still under development, but is nearly complete and is ready to use.  Please report any broken links or problems to us via e-mail.
     
  Important new information (as of April 08): The Joint Commission was planning on revising both the COA and the COT exam content areas, but now the Joint Commission has backed off extensive changes to the COA exam, which were due out in August of 2008.  The new COA exam is now due to be released in August of 2009 with few changes to the exam.  In light if this, it may be that the COT exam will not be changed extensively, at least not in the near future.

Motivation

According to the Joint Commission, approximately 70% of the 15,000 certified ophthalmic medical personnel are assistants, and about 26% are technicians.  I can tell you that this number has not changed much over the years, and this fact amazes me.  Of course, some assistants are recently certified, but many remain COAs for many years.  Another the Joint Commission statistic tells us that certified technicians make more money than assistants do, a significant amount more.  The kicker is that these assistants, in most cases, are doing technician level work.  They're just not getting paid for it.

Don't get me wrong on this.  The "COT" after your name does not mean that you necessarily deserve more money or that you are going to get paid more money.  Those who are motivated to get certified at the technician level are generally more skilled and take more responsibility on the job;  responsibilities such as administration, supervision, and training other OMPs.

Introduction

The Joint Commission has organized the material you need to know for the written exams into "content areas".  The technician is expected to know the assistant level content areas and some additional technician level content areas, which are listed below.  On the left is the approximate percentage of exam questions that will be asked in the particular content area.  The column of numbers in the middle is the approximate number of questions from the particular content area that would be asked on a 200 question exam.  This serves as a guide as to the relative importance (weight) of the particular content area.

Click on the hyperlink, or scroll down to see the sub-listings under each content area.   The study guide consists of comments and recommended reading for each of the content areas.  When you follow a link, a new window may open, so you will need to allow pop-ups on this site if you have a pop-up blocker.  Close the window when finished with the pop-up to return to this window.

There are references and hyperlinks in the study guide to four types of study materials. 

  • Many references are to the book Ophthalmic Medical Assisting, which is the "homestudy" course published by the AAO.  Those applying for assistant level certification are required to complete this course in order to apply for the assistant level exam, so you may have access to this book.  This book has recently been revised (third edition), but the second edition will be fine for study purposes. 
  • Some hyperlinks go to sources on the web.  If one of these links gets broken for some reason, please e-mail me so that I can find a new source for the info.
  • Many of the links go to the modules that are available for CE credit on this website.
  • Some of the links go to PDF files of articles from the old Ophthalmic Trainer Newsletter, which some of you may remember.  These articles are not available for CE credit.

I'm already a certified assistant, can't I just skip the assistant level material and study only the technician level content areas?

This is a dangerous tactic.  About 29% of the exam questions will come from the assistant level content areas.  The questions will not be assistant level questions.  You are expected to know more than an assistant, so the questions will be more difficult on the tech exam.  In the modules available on eyetec.net, we do not separate out different levels of difficulty.  There is assistant, technician, and technologist level information in every module.  We feel that this is information every OMP should know, no matter what level of certification.

How difficult will the exam be?

According to the Joint Commission, the pass rate for the tech exam is significantly lower than it is for the assistant level exam.  Although you would expect this exam to be more difficult, I think the lower pass rate has more to do with a lack of preparation.  If you follow the recommendations of this study guide, you will be prepared.

How much time will it take me to study for this exam?

I would figure about 10 hours for the Ophthalmic Medical Assisting book.  There are over 45 modules on eyetec.net that are relevant to this exam, at one hour each, that would be another 45 hours.  If you figure another 5 hours for practice test questions, you are in the neighborhood of about 60 hours.  If you manage to study 2 hours a day, that would be about a month's worth of studying.

What about practice questions?

Practice questions get you acclimated to the testing environment and they help you study for the exam.  The eyetec.net modules that you will be studying have post-test questions associated with them.  Although, for obvious reasons, we cannot give you the answers to the post-tests, the answers come directly from the module content.  Each module has 15 questions associated with it.

If 650+ post-test questions are not enough for you, the Joint Commission website has books available with practice questions, and eyetec.net has practice tests available.

The Skill Evaluation

If you pass the written exam, you will have to pass a skill evaluation before you become certified.  Follow this link for information on the skill evaluation.
