The national network of Science Learning Centres is a co-ordinating partner in the Getting Practical--Improving Practical Work in Science programme. The principle of training provision for the "Getting Practical" programme is a cascade model. Regional trainers employed by the national network of Science Learning Centres trained the cohort of local trainers at the regional centres. This article describes how the cascade model of training has worked and how the National Science Learning Centre (NSLC) has embedded the programme into one of its core courses for early careers teachers. The Getting Practical wiki site is also introduced.
