The critical behaviour of the spin-1/2 Ising film in a random transverse field has been studied by the use of an effective field method within the framework of a single cluster theory. The equations are derived using a probability distribution method. The effect of the ratio R of the surface exchange interaction to the bulk one, random transverse fields at the surface and in the bulk and film thickness on the phase diagrams are investigated.
