The Centre has a network of teachers who have had specialist training in SLD and can provide tuition - either at their home or in some cases at school, or at the Centre. These teachers are self employed but abide by the code of ethics and quality control policies of the Centre. Professional development and supervision are provided by the Centre. Each teaching programme is individually designed to accommodate the child's particular learning style and individual weaknesses. The duration and frequency of lessons varies depending on the age and needs of the learner, but is usually an hour per week, preferably in school time, particularly for young or distractible children. We recommend that students be reassessed regularly to check progress and adapt the programme if necessary. SLD trained Teachers are in short supply. While every effort is made to find teachers for students needing tuition, we cannot guarantee immediate placement and some students will have to go on a waiting list.
