Yes if you study MSc Speech and Language Sciences at UCL it qualifies you as a Speech and Language Therapist. The course is just called 'Speech and Language Sciences', it has different names at different universities but it leads to qualification to practice as an SLT and includes necessary placements etc. However, don't confuse it with the other Master courses they offer e.g. MSc Language Sciences (Speech Sciences) because they are academic courses without the clinical element that will qualify you as a therapist.
