21 Types of Nurse Practitioner Specialties

Nurse Practitioner

Traditionally, nurses have been associated as adjuncts to doctors; today, nurse practitioners undergo further training and education to be at par with doctors regarding healthcare provision.

Usually, nursing specializations have focused on specific patient populations, but with the rapid evolution of healthcare, NPs can choose to specialize in more fields.

In medical science, specific medical condition-based specializations are also becoming popular. In this blog, we will discuss both pathways.

Population-focused Specializations

The following are traditional specializations that focus on patients according to their gender or age group.

These online programs offer excellent flexibility over traditional methods, allowing NPs to progress in their careers without sacrificing their personal, academic, or professional lives.
