Promoting Independence Through Systematic
Prompt Fading!
Trina D. Spencer, PhD, BCBA-D, LBA!Research Director at IHD!
Research-based Assumptions!
• Excessive and extended use of unnecessary prompts inhibit independence and success of children with disabilities.!
• An effective, yet underutilized, science exists to assist in the systematic fading of prompts so that children with disabilities can be more independent.!
• There are many empirically-supported strategies for fading instructional prompts and paraprofessional support.!

Surface Problems!
Ø Prompt dependency!Ø Reliance on visual prompts!Ø Reduces generalization!Ø Restricts how child can learn!Ø Prevents inclusion!
ACCESS | ATTITUDE | INCLUSION
Ø Decreases teacher’s ownership of students!
Ø Reduced peer interactions!Ø Stigmatizing!Ø Expensive!
• Overuse of unnecessary prompts!
• Overuse of visual prompts!
• Close proximity of parapro!
• Stable use of parapro !

Underlying Problems!
• Most teachers are not trained as instructional designers!
• Instruction is too focused on acquisition not generalization!
• Paraprofessionals are responsible for instruction!
ACCESS | ATTITUDE | INCLUSION
• GenEd teachers’ and systems’ attitudes about ownership!
• Capacity to differentiate within the general education classroom!
• Special Education working conditions!

NO SUPPORTS!
DIFFERENT SUPPORTS!
• All people need supports.!• It is not as simple as supports or no supports.!• Goal should be to move children with disabilities toward
supports that don’t interfere with peer interactions, teacher ownership, and access to quality curriculum and instruction.!

What are prompts?!
• Anything extra to the instruction that ensures that the intended response occurs.!
• Stimulus prompt!• Arrangement of environment!• Modification of material !!
• Response prompt!• Correspondence to the desired response!• Models, gestures, physical guidance!
ACCESS | ATTITUDE | INCLUSION
What are prompts?!
• Prompts are PROGRAMMED!• different from instruction!
• Prompts are TEMPORARY!• not the naturally occurring stimulus!
• Prompts are usually ADULT DELIVERED!• as opposed to self administered, peer delivered, or
environmentally cued!

Stimulus Control is when a response occurs in the
presence of an antecedent stimulus and that
antecedent stimulus reliably evokes/cues the behavior.!

The goal of instruction should be to transfer control from
the programmed stimuli (prompts) to naturally
occurring stimuli.!!
*Prompting is a teaching procedure to help children make the correct response until the response has come under
the control of naturally occurring stimuli.!
Programming for Transfer of Stimulus Control!
1. Select a prompt that currently controls the response but does not disrupt the intended stimulus control.!
2. Select a prompting/fading procedure that will facilitate the transfer, prevent prompt dependency, and reduce errors.!

A standard prompt type will not be effective for all types of responses!
!
Types of Response Prompts!• Visual – pictures, icons, physical models!
• Vocal – vocal models, directions, hints!
• Gestural – eye gaze, pointing, body posture!
• Manual – physical contact!
• Textual – written or typed!
How to Choose Prompt Type!
• Must be currently effective.!• Potential to facilitate or disrupt the stimulus
control with the naturally occurring stimulus.!• Type of response you are teaching.!
• Characteristics of the child.!
• Ease of use.!

Prompting is the teaching procedure to help children make the correct response
until that response has come under the control of naturally
occurring stimuli.!
Effective Prompting Guidelines!
• Prompts should focus students’ attention on the natural antecedent, not distract from it.!
• Prompts should be as weak as possible!• Rule of Thumb: Use the least intrusive prompt necessary to
ensure success. !• The best prompt is the weakest one that will result in the
desired behavior.!
• Prompts should be faded as quickly as possible!• Failure to do so interferes with teaching and creates
prompt dependency!
• Unplanned prompts should be avoided!• Their use leads to incorrect teaching!

!
Fading is the gradual withdrawal of the
programmed prompts necessary for the natural
stimuli to gain control over the response.!
How to Choose Prompting/ Fading Procedure!
• Potential to facilitate or disrupt the stimulus control with the naturally occurring stimulus.!
• Type of response you are teaching.!• Characteristics of the child.!
• Ease of use.!

16
Fading Guidelines!
• Make sure instruction is “clean” before fading.!• Get rid of unplanned prompts first.!
• Begin fading after child has been successful with more intrusive prompts.!
• If you have begun fading and the child struggles to produce the desired behavior use the previous level of prompt to ensure success.!

Training for Paraprofessionals!
• Establish clear roles and responsibilities!• “I thought it was my job to sit next to Alex. If I wasn’t
sitting next to him, others would think I wasn’t doing my job.”!
• “I saw my relationship with the student as the most critical. Now I understand that my responsibility is to help Becca build relationships with her general education teacher and the other students.”!
• “Is it my responsibility to decide when to remove the student when he’s being disruptive? How do I know when I should take him out of the classroom?”!

Training for Paraprofessionals!

• Make rewards social in nature!• Choose a friend vs. get to play on computer alone!
• Ensure the student is sitting near his peers!

You have heard the saying “Be carefulwhat you wish for; you just might getit.” It is a wise adage both school per-sonnel and families might want to keepin mind when considering whether stu-dents with disabilities who are placed ingeneral education classes should be pro-vided with individual paraprofessionalsupport. Virtually everyone having anyconnection with special education cantell you about dedicated paraprofession-als who are worth their weight in gold,so one might ask where the problemlies. In reality, the story of paraprofes-sional supports has many facets.
Some parents understandablyrequest individual paraprofessional sup-port for their child with disabilitiesbecause of their concerns or fears abouthow their child will be accepted, treat-ed, supported, and instructed in generaleducation classes. Yet parents seekinginclusive education through the assign-ment of an individual, full-time para-professional may be working at cross-purposes with themselves. Having anadult by a student’s side for all or mostof the school day can actually interferewith a student’s inclusion as a partici-pating member of the classroom com-munity.
In other situations, parents havebeen told that the assignment of a full-time, individual paraprofessional is the
required admission ticket for theirchild’s entry into the general educationclassroom. A school’s request for anindividual paraprofessional as a condi-tion of placement is often rooted in theconcerns of classroom teachers. Evenhighly competent and willing teachersmay experience some anxiety whenthey are unclear about the expectationspeople have of them in relation to a stu-dent with a disability placed in theirclass. Teachers who feel stretched thin
by issues such as class size and ever-expanding requirements wonder howthey will find the time to meet the vari-ous needs of students with disabilitiesand special needs other than disability.
Meanwhile, principals often experi-ence ambivalence about hiring moreparaprofessionals. Although they maywant to be supportive of parent andteacher requests for paraprofessionalsupports, simultaneously they may becompelled by their central administra-

• Never do anything for the student that he can or should be doing on his/her own.!

• Use as starting point and create intermediate steps (or short term objectives)!
