Intermediate Transfiguration was the required textbook for Transfiguration for third, fourth, and fifth year students at Hogwarts (PA4). (We know that Harry had to buy a copy for third-year Transfiguration but did not need a new Transfiguration textbook in his fourth or fifth year, so we deduce that the same textbook is in use for fourth-year and fifth-year Transfiguration students.) Hermione referred to it again whilst studying for O.W.L.s (OP31).
