If you are a student on CIH accredited courses you have been enrolled as a student member of the CIH for the duration of the course. You can access member only stuff on its website by registering on the website.
Those of you who have successfully complete the Foundation Degree are eligible to apply for full corporate CIH membership. You have to do this; CHS cannot do it for you.
