As a home educating parent and a qualified maths teacher, I think that it is naive to think that HE students can actually sit as many GCSEs as children who are on roll at a school. Firstly, the parent(s) have to choose a suitable curriculum (many GCSEs are unavailable to private candidates). My DD cannot sit Art, any Design and Technology, PE, Drama, Dance etc - as they have a large proportion of practical elements. Secondly, the parent/ carer(s) must find an exam centre where their child can sit the exams - incredibly difficult to do, as most schools do not accept private candidates, or do not have space for English, Maths and Science! Thirdly, the HE parents have to pay for all teaching and learning materials: textbooks, revision materials, science equipment and chemicals etc, exam entry fees, administration fees, invigilation costs(if additional exam invigilators are required). Additionally, even when a qualification is available to private candidates, there may be Non-Examination Assessment or certification which has to be completed by the Exam centre - involving further time and financial cost.My DD is fortunate to be academically able, motivated and have a fantastic support system. However, she and I both find it incredibly frustrating that she probably cannot sit Science GCSEs (certification needed that required practicals have been carried out), or French (speaking assessments cannot be undertaken at our chosen exam centre), despite them being 'open to private candidates'. We can, of course, film her doing the science experiments (where we can buy the necessary chemicals, equipment etc) and hope that showing these videos is sufficient to qualify her to sit the written exams - where practical skills are actually assessed through specific questions. The easier route is for her to study Biology at a local college (alongside the vocational course she wishes to do) after her 'year 11' compulsory education is completed. They don't even offer Chemistry or Physics. Neither do any of the local facilities, which offer courses to EHE learners, provide teaching up to higher standard. Had she remained in a school (where she was under-performing, and actually regressed from year 6), she would have sat 10 or more GCSEs. However, she wouldn't have achieved suitably-high grades in these, and would have hated the entire process of learning.As it stands, she is sitting 2 GCSEs this summer, with a further 4 or 5 planned for next summer. She will then sit her Biology GCSE alongside the vocational qualification she wishes to study at college (with no charge for this). These 6 or 7 GCSEs alone will end up costing upwards of £1400, without any tuition costs (given that she is self teaching, with my support where required). I am a working solo parent, so any support I can provide is outside of normal school hours.
