We study the inflationary period driven by a fermionic field which is non-minimally coupled to gravity in the context of the constant-roll approach. We consider the model for a specific form of coupling and perform the corresponding inflationary analysis. By comparing the result with the Planck observations coming from CMB anisotropies, we find the observational constraints on the parameters space of the model and also the predictions of the model. We find that the values of r and ns for −1.5 < β ≤ −0.9 are in good agreement with the observations when |ξ| = 0.1 and N = 60.
