In a previous work we have proposed that the Prokushkin-Vasiliev higher spinN=2 supergravity on AdS_3 is dual to a large N limit of the N=(2,2) CP^NKazama-Suzuki model. There is now strong evidence supporting this proposalbased on symmetry and spectrum comparison. In this paper we will give furtherevidence for the duality by studying correlation functions. We compute boundarythree point functions with two fermionic operators and one higher spin bosoniccurrent in terms of the bulk supergravity theory. Then we compare with theresults in the dual CFT, where the supersymmetry of the theory turns out to bevery helpful. In particular we use it to confirm results conjectured in thebosonic case. Moreover, correlators with a fermionic current can be obtainedvia supersymmetry.
