Scope of practice describes the boundaries of what a licensed pharmacist is authorized to do — from traditional functions like dispensing and counseling, to expanded activities such as administering immunizations, ordering certain lab tests, adjusting drug therapy under a collaborative agreement, or prescribing specific categories of medication. It is defined primarily by state pharmacy practice acts and board of pharmacy regulations, which means the same license title can carry meaningfully different authority depending on where it is held.
Scope of practice is not static. States have steadily expanded pharmacist authority over the past two decades, often in response to workforce shortages or public health needs, and the pace and direction of that expansion varies widely. A pharmacist’s actual day-to-day scope is also shaped by practice setting, employer policy, and any additional certifications or agreements layered on top of the baseline statutory authority.
Why it matters
Every other practice-authority topic in this glossary — collaborative practice agreements, prescriptive authority, immunization authority, test-and-treat authority — is really a specific slice of scope of practice. Pharmacists who relocate, practice across state lines, or take on new clinical responsibilities need to understand that scope is jurisdiction-specific and does not automatically travel with a license or a certification earned elsewhere.
