Accessing verified on the interface Illuminate\Contracts\Auth\Authenticatable suggest that you code against a concrete implementation. How about adding an instanceof check?

The method isStudent() does not exist on Illuminate\Contracts\Auth\Authenticatable. It seems like you code against a sub-type of Illuminate\Contracts\Auth\Authenticatable such as Illuminate\Foundation\Auth\User.

            return response(view('auth.unconfirmed'), 403);
        }

        return $next($request);
    }
