In this talk I will review the efforts made to measure the volumetric rates of
supernovae, focusing on core collapse supernova, to cosmological distances, z~1. This
includes the recently derived rates from the HST Supernovae Search and the Stockholm
Vimos Supernova Search. I will include a discussion on the various issues that have
to be address in order to minimize statistical errors when deriving supernova rates,
as well as highlighting some of the problems faced when relating supernova rates to
star formation rates. I will also give a brief overview of the CANDELS survey, the
ongoing HST multi-cycle survey aimed at detecting supernovae to redshift z~2 by
searching in near infrared filters. Finally, I will give some examples on the
potential of future telescopes, such as the JWST, to detect supernovae to redshifts
well beyond z~1.
