In April 2006, changes to the managed migration system were proposed that would create one points-based immigration system for the UK in place of all other schemes. Tier 1 in the new system – which replaced the Highly Skilled Migrant Programme – gives points for age, education, earning, previous UK experience but not for work experience. The points-based system was phased in over the course of 2008, replacing previous managed migration schemes such as the work permit system and the Highly Skilled Migrant Programme.
