If you are looking to work in construction, an SMSTS CSCS card is pretty much essential. A CSCS is a physical or virtual card that represents your rank and knowledge within a construction site. Examples of SMSTS CSCS cards include black – managerial card, blue – skilled worker, or white – professionally qualified. To possess a CSCS card, you must first prove your competence and understanding of relevant health and safety requirements. To become a manager, you will need to pass an additional test, the SMSTS test (Site Management Safety Training Scheme).
