Abstract
A number of proposed tokamak thermal transport models are tested by comparing their predictions with measurements from several tokamaks. The necessary data have been provided for a total of 75 discharges from C-mod, DIII-D , JET , JT-60U , T10, and TFTR . A standard prediction methodology has been developed, and three codes have been benchmarked; these `standard' codes have been relied on for testing most of the transport models. While a wide range of physical transport processes has been tested, no single model has emerged as clearly superior to all competitors for simulating H-mode  discharges. In order to winnow the field, further tests of the effect of sheared flows and of the `stiffness' of transport are planned. Several of the models have been used to predict ITER  performance, with widely varying results. With some transport models ITER's predicted fusion power  depends strongly on the `pedestal' temperature, but $\sim$ 1GW (Q=10) is predicted for most models if the pedestal temperature is at least 4 keV.
