First outlined in the 2003 Green Paper 14–19: Opportunity and Excellence, ILPs are intended to map individual 14‐year‐olds' routes through the Key Stage 4 curriculum and allow the monitoring of individual progress. The plan records the learner's achievements at the age of 14; identifies their choices for Key Stage 4, which may include vocational options as well as entitlement subjects, and may also incorporate some element of work experience. It establishes career goals; and provides a means of transferring information about the learner from the compulsory to the post‐compulsory stage of their education. ILPs are revised each year. The growing complexity and flexibility of the 14–19 curriculum signalled in the 2005 White Paper 14–19 Education and Skills has made the use of ILPs a necessity in this phase of education and training.
