- Thyroid disease--palpation of the thyroid gland for size of the gland; Werner maneuver to identify and evaluate thyroid nodules; evaluation of eye changes of Graves disease, DTR testing for hypothyroidism; tremor evaluation; thyroid nodule biopsy
- Use of growth chart for children's and adolescent diseases esp. Cushing's syndrome, thyroid disease, chronic inflammatory diseases

Interpersonal/communication skills:
Residents are observed for interpersonal and communication skills, and appropriately guided to better techniques as appropriate.
Professionalism:
The components of a profession are learning, organization, and altruism. These qualities are fostered in each resident's journey toward becoming a professional. Namely, membership in the professional associations (The Endocrine Society, American Association of Clinical Endocrinology, The American Medical Association, others as appropriate); life-long learning as a component of practice, through organized CME and continual self-study; and a spirit of altruism is fostered in the example of faculty and verbal reinforcement at every step, that all practice is done in the interest of the patient first.
Practice-based learning and improvement:
Deficiencies and strengths of the resident's performance e.g. physical exam are identified and discussed with the resident daily as they occur. On the other hand, life-long education can only be a life-long process. This process in each resident is encouraged by identifying the important endocrine literature that a general internist needs to be aware of the rest of his professional career, including at a minimum (at this writing): Diabetes Care; Journal of Clinical Endocrinology and Metabolism; Endocrine Practice; and Endocrine Clinics of North America. These journals have the up-to-date original research publications, reviews, and guidelines for practice.
Systems-based practice:
Text/references to be consulted:
The major references are the periodicals noted above. The best endocrine book for clinicians today probably is Becker's Principles and Practice of Endocrinology and Metabolism and probably the best for diabetes mellitus is Joslin's "Diabetes Mellitus" by Kahn and Weir. These are often consulted, as well as the current literature in journals as identified above.
Methods of evaluation:
- Daily evaluation is made on clinical performance, especially history and exam using ophthalmoscope, palpation of thyroid, testicular exam, etc.
