Free ATP/ATS Exam Overview

The Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) offers national certification for specialists in rehabilitation and disability technology. The Assistive Technology Practitioner (ATP) exam assesses the knowledge and skills required to work with a disabled individual to select appropriate assistive technology. The Assistive Technology Supplier (ATS) exam assesses the knowledge and skills required to sell and service rehabilitation equipment or commercially available assistive technology products. Both of these exams consist of 200 multiple-choice questions; 150 of these questions are common to both exams, while the remaining 50 are case presentations geared towards either practitioners or suppliers.

The examination covers the following 10 content areas: psychology and sociology (5% of the exam); human anatomy, physiology, kinesiology, and biomechanics (12%); basic etiologies and pathologies (8%); principles of learning and teaching (7%); assessment procedures (15%); service delivery systems and funding for assistive technology (9%); principles of design and product development (9%); basic product knowledge of assistive technology devices (16%); integration of person, technology, and the environment (12%); and professional conduct (7%). In order to sit for these exams, one must meet specific educational and work experience requirements. These requirements are listed in detail on the RESNA website. The ATP and ATS exams are administered annually at the following conferences: RESNA, Heartland, CSUN, ISS, MedTrade, United Cerebral Palsy Association of New York, and Closing the Gap. Individuals interested in taking the exams should find precise dates and locations on the RESNA website.

Answer Key

1. D: EADLs are electronic aids to daily living. All of the listed answers are possible modes of transmission. However, radio frequency transmission (D) is the best choice for use with distant devices like garage door openers because it is not impeded by most materials except for grounded metal. Many more functions can be controlled when using house wiring (A), but it has several disadvantages in this case, including lack of portability and privacy. Both ultrasonic (B) and infrared (C) types are fairly portable, but in each case there must be a direct path between transmitter and receiver, as most materials block their signals.

2. C: The RESNA Code of Ethics lists specific modes of moral conduct to be adhered to; it includes a statement about informing and educating the public about assistive technology, in addition to statements related to moral conduct that other disciplines use. (A) is incorrect because the Standards of Practice actually is broader in scope that the Code. (B) is wrong because both are specific to the Assistive Technology field, although many of the standards are similar to those given in other medical standards of practice statements. (D) is incorrect since neither document actually outlines a specific quality assurance program.

3. B: In pure tone audiometry, thresholds are generally determined at frequencies ranging from 0.125 to 8 kHz as the intensity in dB that the person hears each tone 50 percent of the time in each ear. Decibels represent the amplitude of sound. Intensity (A) also represents a threshold in terms of the frequency of audible sound; that is not the meaning of "threshold" in pure tone audiometry, but the test does give an idea of the range of audible frequencies. Option (C) is one threshold for a normal individual without hearing loss. Option (D) is what is evaluated in another assessment, the speech recognition test.

4. C: The largest component contributing to reaction time is cognitive processing in the central nervous system (CNS). This is true for normal individuals (typically 70 to 300 milliseconds, ms), but it is amplified in people with apraxia who have an inability to perform complex movements through CNS involvement (such as with brain damage) but have intact peripheral systems. Normally typical times are up to 38 ms for sensory reception (A), from 2 to 100 ms for neural transmission to the CNS (B), 10 to 30 ms for neural conduction to the muscle (D), and 30 to 70 ms for a fourth component, latency and activation time of the muscle.

5. A: The first step generally is to assess seven functional hand grasp patterns, because the ideal control sites are the hands and fingers. Option (B), in which the individual uses his or her thumb to point to corners or touch them by hand using a range and resolution board, is usually performed after the functional grasp patterns. If the person cannot use his or her hands for controls, then range and resolution are determined using less preferable sites, which in decreasing order of preference are the head (D) or mouth, the feet (C), and arms or legs. Sometimes the chin, forehead, or eye movement is used for control.
