Pharmacy, with more than 230,000 practitioners today, is the third-largest health profession in the United States. Research on the national pharmacist workforce points to a continuing shortage of pharmacists, related to growth in medication use, the aging of the baby boomer generation, and the emergence of more clinical activities within pharmacies. Surveys that track shortage levels showed that there was a slow downward trend in the severity of shortages up until fall 2005, followed by higher shortage levels during the past year. Changes in shortage levels appear to parallel growth in prescription medication usage. WICHE’s Professional Student Exchange Program (PSEP) allows students from states that do not have a public school of pharmacy to pay reduced tuition to a cooperating institution in the West. Sending states determine the number of new students to be supported each year. In 2006-07, 40 students from Alaska, Hawaii, and Nevada attended 16 cooperating pharmacy schools.
