Appointment as Associate Scientist may be given to an individual who has demonstrated the qualities of superior achievement expected of an established and independent research scientist. The following would be among those qualities: the capacity to identify significant and relevant research questions; the ability to formulate and carry out research to answer these questions and to sustain a viable, externally funded program; the ability to exercise superior judgment and discrimination in the interpretation of research results; the motivation to present the results of this research to the judgment of others through lectures, publications and papers; and finally, the recognition of the excellence of research as demonstrated by a national reputation. Associate Scientists are expected to pursue independent research, although this may involve collaboration with other scientists. They are expected to take an active interest in the welfare of the Institution by such activities as the preparation of research proposals, participation in Department or Center affairs, participation in Education programs, service on Institution and national committees, and providing assistance and advice to their colleagues.

Appointment to Associate Scientist occurs through national advertisement, or by promotion from Assistant Scientist at any time prior to completion of the initial 4-year term (but almost always near its conclusion). Appointment is normally for a 4-year term, except in certain circumstances when the President and Director may recommend a 5-year term to the Executive Committee. Promotions from Assistant Scientist are normally for a 4-year term, except in certain circumstances when the President and Director may recommend a 5-year term to the Executive Committee.

When required to meet extenuating personal circumstances that could seriously inhibit professional productivity (e.g., disability of the employee, family illness requiring extended care, child rearing or bearing, or dependent parent care), with a timely written request via the Department Chair to the Director of Research, the term can be extended for up to 12 months. Using this option does not eliminate the possibility of a Staff member being considered for promotion at any time during the term of appointment.
