Level 3 Diploma/Certificate Medical Science

Course ID

Medical Science is the science of dealing with the maintenance of health and the prevention and treatment of diseases. The Level 3 Diploma in Medical Science is for learners who are interested in careers related to healthcare and medical research.  Medical scientists are at the forefront of healthcare services, as they are vital in the diagnosis of disease, determining the effectiveness of treatments and searching for new cures.

The Level 3 Diploma in Medical Science is for post 16 learners who have already enjoyed and been successful in science. Typically learners starting this qualification will already have science qualifications at level 2, e.g. GCSEs in science subjects or GCSE Applied Science (Double Award).

The main purpose of the qualification is to provide learners with the knowledge, understanding and skills in key scientific principles to support progress to higher education or employment in areas of Medical science, such as job roles in physiological sciences or clinical laboratory services. The qualification covers the key topic areas of health, physiology and disease, as well as providing the opportunity to study the areas of pharmacology, physiological measurement, clinical testing and medical research. In order to achieve the Level 3 Diploma in Medical Science learners are required to complete 6 units. Each unit has a clear medical science purpose which focuses the learning of scientific knowledge, understanding and skills into a meaningful context.

This qualification equips learners with scientific knowledge and understanding, as well as practical skills that would support progression to a range of job roles within health care. Job roles such as those  within the areas of life sciences, i.e. carrying out a range of laboratory and scientific tests to support the diagnosis and treatment of disease, this could include microscopic examination of tissue samples, analysis of blood cells to investigate anaemia or analysis of samples to identify the cause of an infection. Alternatively there would also be opportunities to progress to job roles within the physiological sciences, working directly with patients, measuring and evaluating particular organ and systems, such as scientists working in neurophysiology recording the electrical activity in the brain.

A significant proportion of career opportunities in this sector are at degree level. When supported by other appropriate qualifications, the Level 3 Diploma in Medical Science will enable progression to higher education to a range of Applied Science programmes, such as biomedical science, life sciences, and physiology.   The Level 3 Diploma in Medical Science is one of two qualifications offered by WJEC in this subject area. The level 3 Diploma is equivalent in size to one A level. WJEC also offers a Certificate in Medical Science which is equivalent to half an A level. Studying the level 3 Diploma in Medical Science allows time in the curriculum for other qualifications to be studied alongside it, these would typically be A levels such as Psychology or Chemistry or another Applied General qualification in an area such as Health and Social Care or Environmental Science. The level 3 Diploma in Medical Science is intended to be an Applied General qualification.
