N2 - In the N=1 supersymmetric coset model based on (AN-1 (1)⊕ AN-1(1) AN-1 (1))at level (k, N), the lowest N=1 higher spin supercurrent with spins(5/2,3), in terms of two independent numerator WZW currents, is reviewed. By calculating the operator product expansions (OPE) between this N=1 higher spin supercurrent and itself, the next two N=1 higher spin supercurrents can be generated with spins(7/2,4) (4,9/2). These four currents are polynomials of degree 3, 4, 4, 4 in the first numerator WZW currents with level k. The complete nonlinear OPE of the lowest N=1 higher spin supercurrent for general N is obtained. The three-point functions involving two scalar primaries with one spin-2 current or spin-3 current are calculated in the large N limit for all values of the 't Hooft coupling. In particular, the light states that appeared in the case when the second level was fixed by 1 are no longer light ones because the eigenvalues are finite in the large N limit.
