From the MLA website:
The Academy of Health Information Professionals (AHIP) is MLA's peer-reviewed professional development and career recognition program. The academy recognizes the personal investment of time and effort required for exemplary professional performance and for contributions to the association and to the profession.
The academy provides a structure for individualized professional development for all health information professionals, no matter how long they've been in the field. Whether you are new to the profession or have been working in it for years, the academy has a membership level and professional development guidelines for you.
For the professional librarian, academy membership provides a structure for professional development. From the initial needs assessment and mentoring of provisional members to the recognition of professional accomplishments of distinguished members, the academy is here to support professional librarians. Membership in the academy recognizes and encourages professional activities, and the AHIP designation demonstrates this commitment to professional development.
Employing institutions view academy membership as proof that their librarians are committed to their own professional development and continuing education. Institutions who value academy membership recognize and reinforce the importance the health information professional plays in their organization.
