I have no idea, grand total wise, how many "programs" exist that, more or less, are similar to PANTS. I suspect there are at least several.
Probably the biggest difference among them is methodology rather than curriculum content.
Here in the USA, there are 'free-lance' fee for service consultants in this area. I don't think its realistically accurately knowable whether
these consultants work primarily training teachers, or some combination of teacher training and short term in-classroom work, OR whether the school
system simply puts the onus on classroom teachers of the "additional related duties" scheme.
Because each school system is an entity unto its own self, and private schools are in their own 'world', it's very difficult to get an overview of
all of this, i. e., it is not unusual for public school districts to ignore state required reports on this or that matter, and I can just imagine how
much, or how little, effort ever goes into making any given report as thorough/accurate as possible.
I'm familiar with a similar program called "Circles"; this URL is from a vendor of same:
Once upon a time, Circles became an overnight 'it's all the rage' affair for individuals with intellectual disabilities in schools, residential
programs, sheltered workshop programs (YES, I realize I'm using politically incorrect labels, but that's what they were called for years and
IMO Circles took off like a rocket cause of a fear of liability by the powers that be at all levels. In some ways that was not such a bad thing from
the "something is better than nothing" perspective. Were there any issues of "clients/students" possibly misunderstanding the "warning signs"
and making "inaccurate" "accusations"? That's why "management" gets paid big bucks. Firing someone almost always is appealed--and
lawyer/union involvement is commonplace.
During this period the State via the legislature even set up a hot line/agency to report abuse--but it was nothing at all re authority/scope/resources
that the State child protection services had--THAT WAS NO ACCIDENT/OVERSIGHT.
Believe you me, who of the staff was "qualified" to "teach" such a program hardly mattered as was the question who of student/clientele could
actually have ANY comprehension. Yet there are clearly students/clientele who had good receptive language, but poor expressive language skills, which
of course always leads to the question of just what they are comprehending.
