Sandhurst is a training program, not an education program. However, a couple of TOs do have education (v training) content. Of course, all education has a training component while all training has an education component - think of the difference as between critical thinking and acquisition of skills. As Wilf and others have pointed out, there are many roads to officership. I would add that the American Officer Candidate School source of commissioning is as important as ROTC or the academies. I would also note that two of my students at OU this year are former enlisted who will be commissioing shortly through ROTC - one USAF and one US Army. In the Army this used to be known as Green to Gold.
