Hi, welcome to silkysteps :) all the organisations are aiming for the same outcome ie. for the child or young person to have a successful, positive and rewarding life.They each work in different establishments, places or environments with children & YP that come to them or contact them in different ways and for differing reasons via personal & external factors.
There is a very informative
thread here that helps introduce the professionals involved with abuse and harm.
The
'About us' and what we do page of NSPCC will also help.
People you may meet is a booklet for parents that lists a range of professionals and is good to see what is involved with each role, the pages of nationalcareerservice.gov.uk also lists job profiles, their roles and responsibilities -
