The increasing occurrence of outpatient medical care has led to the need for more and better medical education in the clinic. the Wisconsin Inventory of Clinic Teaching (WICT) was developed to improve the teaching of attending doctors in a general internal medicine clinic. The items on the inventory were derived from interviews with residents and attending doctors. The inventory was shown to have validity, and to be reliable with internal consistency correlations. We found an interesting disparity between attending doctors' and residents' expectations concerning clinical teaching. The instrument is in use as part of a teaching improvement programme for attending doctors in a general internal medicine clinic.
