The Introduction to BSL course is designed to be just that; an introduction to British Sign Language.

The Level 1 support course covers 35 topics, compared to the 9 in the Introduction course. Where the topics do overlap, the level 1 support course generally covers them in more detail, and with a greater range of examples and reference to wider BSL concepts. The Introduction course focuses more on specific vocabulary; while the Level 1 support course develops to include much more complex situational and extended signing, including concepts such as placement and sign order.

The level 1 support course is designed to cover the full range and complexity of signing needed to achieve a level 1 qualification and beyond. The Level 1 course also allows access to the Online BSL dictionary, which has over 950 signs.
