Exam Objectives

CompTIA goes to great lengths to ensure that its certification programs accurately reflect the IT industry's best practices. The company does this by establishing Cornerstone committees for each of its exam programs. Each committee comprises a small group of IT professionals, training providers, and publishers who are responsible for establishing the exam's baseline competency level and who determine the appropriate target audience level. After these factors are determined, CompTIA shares this information with a group of hand-selected Subject Matter Experts (SMEs). These folks are the true brainpower behind the certification program. In the case of this exam, they are IT-seasoned pros from the likes of DHL, RFID Journal, and ODIN Technologies, to name just a few. They review the committee's findings, refine them, and shape them into the objectives you see before you. CompTIA calls this process a Job Task Analysis (JTA). Finally, CompTIA conducts a survey to ensure that the objectives and weightings truly reflect the job requirements. Only then can the SMEs go to work writing the hundreds of questions needed for the exam. And, in many cases, they have to go back to the drawing board for further refinements before the exam is ready to go live in its final state. So, rest assured-the content you're about to learn will serve you long after you take the exam.

Note 

Exam objectives are subject to change at any time without prior notice and at CompTIA's sole discretion. Please visit the certification page of CompTIA's website at www.comptia.org for the most current listing of exam objectives.

CompTIA also publishes relative weightings for each of the exam's objectives. The following table lists the five RFID+ objective domains and the extent to which they are represented on the exam.

As you use this Study Guide, you'll find that I have administered just the right dosage of objective knowledge to you by tailoring my coverage to mirror the percentages that CompTIA uses.
