Web-based technologies have made possible two new kinds of post-master's graduate programs: professional doctorates and certificates of advanced graduate study (CAGS).

Many professional doctorate and CAGS programs don't require practitioners to quit their jobs or relocate, but they do offer preparation for advanced practice along with the same research training provided by a traditional doctorate (often in much less time). A CAGS is a prestigious post-master's credential used widely in other fields, like education, occupational therapy, and dentistry. In each of those fields, the professional credential (for education, a master's, for dentistry, a DMD or DDS) is followed by a CAGS after gaining substantial professional experience. The CAGS becomes a symbol of advanced training and professional excellence.

Northcentral University, Tufts University, and Northwestern University all have CAGS programs in public policy, public administration, or planning, though each takes on a different structure. Northcentral only offers courses online, which are taught with a 1:1 faculty-to-student ratio. By contrast, the Tufts program implements a cohort model and combines the online with two, one week, on-campus residencies—during the summer before and the summer after the online academic year. As an added bonus, the Tufts program provides the opportunity to fulfill two years of certification maintenance requirements for the American Institute of Certified Planners. The Northwestern University CAGS enrolls new students on a rolling basis for courses offered online, on campus, or a combination of both.

The University of Southern California and Northeastern University offer professional doctorates in planning and public policy. The University of Southern California's professional doctorate is practice-oriented, requires regular residency in Los Angeles for three to four years, and features a capstone research project. At Northeastern University, Dr. Estrella-Luna describes the Doctorate in Law and Policy: "Through structured learning, the program builds up a person's skillset and helps them develop a new understanding that propels their career forward. Students become public academics and solve problems through research." Students take accelerated courses online for two years, but meet with their cohort once a month in Boston during the duration of the program.

While exploring options in continuing education, ask yourself: What is your ideal time commitment? What is your need for flexibility? Do you plan to continue working full-time? What is your working style? Are you hoping to extend your network? These questions might guide you to the type of program best suited to you.

CAGS programs in planning and public policy generally last for one year, while professional doctorates will take at least two years of full-time study and roughly four years of part-time study.
