There are three tests involving angular sizes of radio sources which appear to be at least as good as the traditional N(s) test. These have not been used extensively until now, probably because of a lack of high resolution angular size measurements over a wide range of radio source flux densities. This situation is changing rapidly especially with the increasing resolution and sensitivity of aperture synthesis telescopes. In this review these methods and some of the recent results are discussed.
