Discrete Trial Teaching (DTT)
This is accomplished by simplifying requests, prompting the child to make the
correct response and providing abundant reinforcement for socially appropriate
behaviors. At the same time, failures are minimized. Ensuring the child's
motivation to participate in the learning process is a key element in behavioral
interventions
In brief, the intervention is based on operant techniques and the shaping of
behavior through reinforcement of successive approximations, prompting and
fading procedures, and use of positive reinforcers that are functional (i.e.,
serve the intent of increasing behavior). Examples of such reinforcers are small
bites of food, play with a favorite toy, looking at a favorite book, and social
rewards such as verbal praise, tickles, hugs and "rides through the air." As
intervention progresses, food and other "artificial" reinforcers are replaced,
whenever possible, by more, social, and everyday reinforcers. The intervention
is structured so that "positive" behaviors are maximized through prompting and
positive reinforcement. High rates of inappropriate behaviors, such as
aggression or self-stimulatory behaviors, are reduced by being ignored and by
teaching alternate, more socially acceptable forms of behavior. The intervention
progresses very gradually from teaching beginning learning skills such as
sitting in a chair, matching identical objects and basic imitation to verbal
imitation skills, elementary receptive language, and establishing the beginnings
of appropriate toy play. Discrimination learning plays a dominant role in
teaching all skills.
Once the child has mastered basic tasks, the second stage of the intervention
emphasizes the teaching of expressive and early abstract language and
interactive play with peers."

Your ABA team has 2 important components - the consultant (who manages the
program) & the therapists/tutors.
Consultant
- Role of Consultant is to manage the program, troubleshoot problems and
guide the program with both short term & long terms goals in mind.
- Find the consultant that suits your child: Each child is unique – a
consultant may be wonderful for one child and not for another eg: some
consultants are very academic driven; others are very good with behavioral
issues. If you have a child with major behavioral problems, your program won’t
progress fast if you team up with a consultant that doesn’t know what to do
about it. To find out what works for you, talk to other parents. Talk to the
consultant as well to find out whether they can handle the unique challenges of
your child.
- Can be local or out of area.
Local Consultants:
Advantages: will be more hands on in your case. Able to have more team
meetings, do classroom observations, will be able to attend IEPs etc.
Disadvantages: Long waiting lists. Have to check quality of person you
are hiring.
Out of area Consultants :
Advantages: worth it if you are able to get a really really
good/famous consultant. They have the vision & know how to drive your program
toward a long-term goal. The very good consultants are able to resolve the tough
behavioral challenges that even most consultants are stuck with.
Disadvantages: more expensive as you have to pay for flying them in,
hotel charges etc. Their visits will be less frequent and that is not good for
programs that need lot of supervision & constant changes.
Therapists
- Role of the therapist(s) is to work hands on with your child.
- Some programs differentiate between senior & junior therapists.
- Therapists on the case are trained by the consultant, district or you
depending on the type of arrangement you have set up.

i. Private agencies
Agencies can be both local (like CARD, Stepping Stones) or out of area/state (eg:
Autism Partnership)
Advantages.
- Provide both consultant & therapists so it’s a total package
- Saves you searching, hiring & maintaining therapists.
- Agency is responsible for training the therapists.
- If they are NPA (non public agency) can get your district to fund them. NPA
means that the district can recover some of the costs from the state.
Disadvantages
- No control over quality of therapists. Agencies go through lean periods and
sometimes there are not enough therapists on the case.
- Cost: Typically agencies bill $100-$150/hr for consultants & anywhere from
$30-$80/hr for therapists (senior & junior) + team meeting hrs + material
preparation hrs etc.
- No control over who the consultant in your case is going to be. Often senior
therapists are promoted to consultants, which may or may not work out well for
your case.
ii. Consultant & Therapists: separate packages
Advantages
- This option is often more cost-effective for parents.
Disadvantages
- You/district have to find & train therapists. Therapist availability
fluctuates.
iii. District’s in-house ABA programs.
-
Lot of school districts have now started their own brand of in-house ABA.
iv. Supplementing School ABA hours.
-
Another possible combo. If the district gives you some ABA from their in-house
program, you can “supplement the hrs” by having your own therapists provide
additional hrs. Make sure everyone is doing the same program so as to not
confuse the child ie: the private therapists should be attending the team
meeting and following the same program. (Note if you have a young child, there
is no reason why the district should not be funding all the hrs the child
needs).
Local ABA
Providers

- Many School districts will give ABA for ASD these days as they have been sued so many
times in the past.
-
By starting in-house programs districts have been able to save both money
(school therapists get $15/hr) & satisfy the parents.
-
By law the district may be required to give you ABA but not necessarily the
“best ABA” so quality varies.
-
Often the argument is that your child is “too old” for ABA. Not true – good ABA
helps the kid improve at any age. Often the onus is on you to prove this.
-
ABA tutor hrs include time for following – team meetings, material preparation,
tutor training. While these are necessary, focus on how many hrs of 1:1 tutor
time your child actually gets. Make sure the hrs allotted to you is not eaten up
by the other stuff. List 1:1 time separately in the IEP and hrs for the rest are
in addition.
-
Consider also that 1:1 tutor tutor time is not actually fully 1:1 time eg: it
takes the tutor 15-20 mins at beginning of session to set up & same time at end
to write notes & tidy up. So actual 1:1 time is a lot less than it looks on
paper. If you can work these into your IEP even better.
-
Some agencies distinguish between senior & junior therapists. You do need a good
amount of senior therapist time. Specify the breakup in the IEP so that you
don’t get shortchanged. Make sure the senior on the case is there not just to do
“material preparation” but also works hands on with your child.
-
Also make sure each therapist on the case works at least 2x/week with your
child. Anything less would result in them spending a lot of extra time at the
beginning of each session trying to read the binder to see what has happened in
the last one week.
-
ABA consultant hrs include time for team meetings, tutor observation & classroom
visits if any. Accommodate all these. Also work in how often the consultant will
visit your case. A closely supervised case is preferred so the consultant should
be on the case at least every 2-3 weeks.

-
It’s a good idea to get familiar with IDEA (Individual with Disabilities
Education Act). It may sound very intimidating but you don’t have to know all of
it – just the parts that apply to you. A number of special education lawyers
have written books with their interpretations of each section & these are easier
reading as it is more in layman’s terms. PHP library would definitely have books
on it. A very popular one is Special Education Law by Pete & Pam Wrightslaw.
-
This is especially for parents of young children (esp under 5) trying to get
ABA. IDEA does mention “40 hrs/wk ABA ” in several places – you should use this
info to your advantage to get the hours you need for your child. Especially read
the chapter(s) on “Infants & Toddlers”. The argument for ABA as a treatment for
autism is that it is the only method that is backed by research (Lovaas’s 1973
Young Autism Project study). Again I am not a lawyer or a parent advocate so
don’t take my word on it & do check what exactly the law says.
-
ABA becomes a much harder case to justify with districts once the child is
older.
- A lawyer is someone who has the law degree & is certified to practice in this
state.
-
A parent advocate does not have a law degree. It is simply a person who is very
familiar with the law, gets paperwork together, reviews your case, will
accompany you to the IEP & help you secure the necessary services for your
child.
-
In many cases Parents of older children who have had success in dealing with
districts choose to become parent advocates in order to help other parents.
-
A lot of parents are able to get the services on their own from SARC/District,
while others have needed the help of a parent advocate.
-
A good parent advocate should be able to get you a decent amount of ABA hrs,
speech & OT.
-
A parent advocate is also significantly cheaper than a lawyer.
-
My understanding is that you need a lawyer only if you are suing the district or
going into arbitration/mediation. In which case you can directly hire a special
education lawyer or the parent advocate will hire one for you.
-
You need to contact a parent advocate early on. Don’t expect one to be available
the day before your IEP/IFSP. They need time to review your case history,
diagnosis, any evaluations, any reports etc. A number of them have long waiting
lists so get them early. They should bill you only for the hrs they actually
spend on your case + IEP attendence hrs etc.
-
Quality of parent advocates vary & I have heard different stories from various
parents about their parent advocates – from good to downright ridiculous. The
general feeling I get overall is that a parent advocate is useful when trying to
get funding for services like ABA, speech & OT but less useful when it comes to
an appropriate classroom placements (which is usually an issue only when the
child is older). However a really really good parent advocate should not have a
problem with that either.
Local (Bay Area) Parent Advocates & Lawyers

(pitfalls to watch for)
-
You rarely get so many hrs of therapy. Hours get taken away by things like
classroom time, school SLP & School OT & team meetings.
-
Excellent therapists are few & far between. When they become very good, they
become consultants & stop working hands on with your child. But if you are
fortunate enough to have a good therapist, tape each & every session & learnt
what she does & duplicate it with your child.
-
The supply & demand situation is such that even mundane therapists charge a lot.
Training in a lot of the programs for them mediocre.
-
High therapist turnover. Being a therapist is hard work – there are jobs that
are less demanding – they get married, get pregnant and leave (I’ve had 5
therapists get pregnant over the last 5 years & quit)
-
Too much time seems to be spent on taking data & writing notes on the parts of
the therapists.
What is ABV (Applied Verbal Behavior)
-
In short it is simply ABA with a lot of focus on the “verbal behavior”. ABV is
based on Skinner’s analysis of language.
- Dr Vince Carbone, Dr Jim Partington & Dr Sunberg have done a lot of research in
this area and are major proponents of this approach. Most good ABA programs do
incorporate a lot of verbal behavior. The terminology used in AVB is the
terminology used by Skinner. But if you look beyond the terminology, the
terminology in AVB essentially refers to the same things as in ABA.
