The American Library Association (ALA) provides accreditation for master's programs in librarianship across the United States, helping provide skilled professionals in many types of libraries and information centers. The ALA Core Competencies are established for all professional librarian roles. As such they are broad and cover much more content than any librarian directly needs. Little research has been done on the use of the competencies, and none was found on how librarians feel about them. Q Methodology is a unique mixed methodology which provides an opportunity to study participants' viewpoints. Results of this study were three factors: the Patron-Focused librarian, the Teaching & Learning librarian, and the Research & Knowledge librarian. Each factor demonstrated certain traits, with some overlaps and some distinguishing characteristics. Stakeholder Theory, the idea that anyone who is impacted or affected in some way by the actions of an organization is therefore a stakeholder, was the theoretical framework used in the study. As a result of this connection, the implication that the librarian factors each affect various stakeholders is clear. This study begins a direction of research that warrants exploration to fully realize the value of competencies to librarians in different positions and types of libraries.
