Lifelines is a coherent 5-year course on social and personal development designed for 11-17 year olds of all abilities. The course is suitable for use on a year-by-year basis although the structure is sufficiently flexible to allow teachers to use the sections selectively. The topics covered in each book vary to reflect the maturity and interests of the target age group. Each book covers the key areas of education for personal relationships, social education, health education and study skills.
