to review the documented goals, strengths, and present levels of performance over
time of both individuals even without the real-time input of an individual who was
very familiar with the learner.
After profiles were created, each category (not used, emerging, mastered,
and surpassed) was scored by dividing the total in each category by total number of
boxes (e.g., emerging =
= 34%) which then allowed each category to be
compared. The levels of communication skills (pre-intentional behavior,
intentional behavior, unconventional communication, conventional
communication, concrete symbols, abstract symbols, and language) on the CM
profiles were then examined using the same formula (Probst, 2017). This data was
used for the analysis of communication development in the case studies.
An examination Terry's CM profiles showed mastery of only 19% of the
communication skills on the CM by the age of eighteen (see Figure 2). Although
Terry's communication skills trajectory increased (skills mastered improved from
5% to 19%), this development occurred over sixteen years.
