Let p be a given non negative integer. For any m ∈ N, let Bem,p : C [0, 1 + p]  → C [0, 1]  Bem,pf  (x) = mX +p k=0 pem,k(x)f(k/m) be the Schurer operators (introduced and studied by Schurer, K., in 1962). Some approximation properties were studied in ([4]). In the present paper we study properties of simultaneous approximation for Bem,p. As particular cases, we get similar properties for Bernstein operators.
