In the past 10 to 15 years, new kinds of doctorate degrees – in fields
that had never had doctorates before – have burst onto the higher
education scene in the United States. These new ‘professional practice
doctorate’, or PPD, degrees have emerged in at least a dozen fields,
ranging from physical therapy to bioethics.
Some of these newly created doctorate degrees are now required for a
person to enter a professional practice. In other fields, although they
are not (or not yet) required, these doctorates have become the
normative degree.
Nor is this just a US phenomenon: new professional doctorate degrees
have been created and programmes for them are growing rapidly in Canada,
the United Kingdom, Ireland, Australia and elsewhere.
Professional practice doctorates differ from PhDs in several ways; most
are shorter than PhDs – in some cases, only slightly longer than the
masters programmes they replace. In the US, most do not require original
research, but they do include a clinical component.
Beyond this, there is little agreement on what they are or should be.
Yet, like PhDs, they use the title ‘doctorate’, require at least some
study beyond the masters level and are intended to confirm the highest
level of achievement.
Phenomenal growth
The growth of newly created professional practice doctorates in the US has been phenomenal.
Programmes for them skyrocketed from nearly zero a decade ago to more
than 500 programmes in at least a dozen fields today, with over 10,000
degrees awarded just in 2012. For example, doctor of nursing practice
programmes increased from just two in 2002 to 217 in 2012; nearly 100
more programmes are in the planning stage. What’s driving this growth?
Supporters of the new doctorates state that they are needed to respond
to the growing complexity of professionals’ work environments, rapid
expansion of knowledge underlying practice, and increases in
technological interventions. While there are some indications of these
factors, in most fields the evidence is limited.
For example, the difference between masters and doctoral programmes in
physical therapy is on average just 12 weeks, and doctorate holders do
not have higher licensure pass rates; if increased labour market
complexity were the main reason to require doctorates, one would expect
greater differentiation between masters and doctoral degrees and greater
student success.
Overall, it is not evident that these doctorates have led to higher
salaries or career advancement for professionals or significantly better
outcomes for clients, although it may be too soon to determine
outcomes. Rather, based on my research, I conclude that in most fields
professional associations’ and practitioners’ pursuit of greater status,
autonomy and control has been the main factor driving the creation of
new doctorate credentials.
Once these doctorate degrees are established, institutions have felt
pressured to offer doctoral programmes either because accreditation
mandated it or because they felt they would be less competitive
otherwise. For many formerly non-doctoral institutions, these new
doctorates also provided an opportunity to take a long-desired step into
doctoral work.
It is important to note that situations do differ among fields,
programmes and institutions. Nevertheless, much of the adoption of these
doctorate degrees seems driven by credential creep, followed in many
cases by mission creep.
Why the growth of PPD degrees matters
The resource implications of the professional practice doctorates are substantial.
First, there seems to be a domino effect in health fields, with the PPD becoming the required or normative degree for entering practice in one field after another. Second, while most new growth in the US has been in health fields, new types of PPDs have been started in a variety of fields.
Third, many of the new programmes are expensive, so even limited
expansion requires more resources. At a time when most institutions face
shrinking resources, this means either redistribution of resources from
other programmes or institutions, a higher workload burden on faculty,
or higher tuition fees and higher foregone income burdens on students.
Indeed, partly because of public disinvestment in higher education,
students are bearing the brunt of increased programme costs. For
example, median total tuition and fee costs for doctor of physical
therapy programmes in US public institutions were 63% higher than for
masters programmes in 2010; in private institutions, they were 14%
higher.
Higher tuition and longer periods of study will likely increase student
debt and may reduce access into the profession, especially since
financial support for these programmes is meagre in most cases.
PPDs also raise unresolved questions.
For example, what should a ‘doctorate’ mean? Should profession-specific accrediting bodies – which play important roles in setting standards for programme effectiveness – also determine which degrees institutions offer in these fields? Finally, the fundamental issue for public policy is the ultimate impact of new PPDs on clients, organisations and communities. New requirements could lead to fewer professionals, especially in already under-served communities.
On the other hand, if PPD training enables professionals to serve their
clients more effectively, meet new and more complex needs and, in the
words of advocates, transform the organisations and settings in which
they work – and do so without reducing access to services – the added
resource costs to individuals and the public may well be worthwhile.
Those outcomes are still unknown.
