Information – facts which are given or that you learn, e.g., a college prospectus gives you information about what courses the college offers.
Advice – an opinion or a suggestion about what you should do in a particular situation, e.g. if you say you want to be a hairdresser you might be told that you could go to college or do an apprenticeship and the person offering advice might tell you what they think would be best for you.
Guidance – a confidential discussion and exploration of your ideas, skills, abilities, interests, motivations, etc with a qualified practitioner (level 4 or 6 in IAG) who supports you to weigh up your options, do the reality checking, and take ownership of the decisions that you make. Guidance is not about telling the person what they should do or even protecting them from poor decisions but working through their ideas. Hence it takes time.
