RESNA ATP EXAM QUESTIONS AND
ANSWERS (VERIFIED AND UPDATED)
Numeric Code - ANS AAC coding technique in which a number stands for a word, phrase, or
sentence. Communicate quickly with fewer keystrokes
Abbreviation Expansion - ANS AAC device automatically expands the abbreviation into the
expanded word. abd = abduction
Coverage Vocabularies - ANS provide basic communication topics as well as concepts for
people who cannot spell - words, symbols, or pictures
Acceleration Vocabularies - ANS intended to increase the rate of communication for people
who can spell - letter codes stand for words, phrases, and sentences
Semantic Encoding - ANS pictures/symbols/icons represent words, phrases, and sentences.
Icons have potential for multiple meanings
Predictive Selection - ANS Icon prediction feature used with scanning
Predictive Scanning - ANS predictive approach based on the frequency with which certain
letters follow others in English
Word Prediction and Word Completion - ANS displays words or phrases a user is typing based
on what has already been typed
@2026/2027 ALLRIGHTS RESERVED.
,Fixed Predictive Devices - ANS stored vocabulary that never changes - very predictable and
helps the user develop motor and cognitive patterns that make retrieval faster
Adaptive Predictive Devices - ANS change the order of words keeping most frequently used
words at the top of the list
Eye-Controlled Communication Systems - ANS for people with severe limb limitations but
good eye and head control.
Keyguard - ANS cover made of plexiglass or plastic that fits over a keyboard for people who
have difficulty pressing the right key or who produce extra movements as they move key to key
Automatic Scanning - ANS device presents available choices continuously. Users must be able
to wait for selection and activate accurately at the correct time
Step scanning - ANS press switch to move from choice to choice. Must active another switch
or wait for acceptance time to elapse to choose. Motor fatigue has potential to be high with this
method
Inverse Scanning - ANS User holds switch to scan, releases to select
Instructions - ANS ATPs should provide written instructions for all equipment and make sure
it is accessible to client, cognitively and physically. Provide supplemental instructions if
necessary
Motor Skills Training Program (3 stages) - ANS 1. Activate switch and associate switch with
result
2. Activate switch at a certain time consistently
3. Increase array that the user can consistently select in order to improve scanning selection

, HAAT - ANS Human Activity/Assistive Technology Model
Human
Activity
Assistive Technology
Context - ANS Operator using AT system properly?
Does the system allow user to meet goals for activity?
Does the system bridge the gap between the skills the consumer has and the skills needed for
the activity?
Does the system perform in the physical, social, and cultural environment?
Follow-up versus Follow-along - ANS Follow up = activities that occur immediately after AT is
installed
Follow-Along = activities that occur over a longer time span, often over a life-time
Scanning - ANS Most common type of INDIRECT selection in which consumer uses a switch to
select option when highlighted
Directed Scanning - ANS user initiates scanning process then selects option with a joystick or
other switch. This is the fastest indirect selection method
Acceptance Time - ANS the length of time a user pauses at a choice during directed scanning
Coded Access - ANS selection method in which the user completes a sequence of movements
as a code for each item in a selection set
Spatial Characteristics of a Control Interface - ANS size, shape, weight, number of targets, size
of targets, and amount of space between targets
