Abstract We review the coset construction of conformal field theories; the emphasis is on the Hilbert spaces for these models, especially if fixed points occur. This is applied to theN=2 superconformal cosets constructed by Kazama and Suzuki. To calculate heterotic string spectra we reformulate the Gepner construction in terms of simple currents and introduce the socalled extended Poincaré polynomial. We finally comment on the various equivalences arising between models of this class, which can be expressed as level rank dualities.
