Open to all full-time undergraduate students studying a biology-related subject.

Associate (AMRSB)

If you have been awarded a degree containing at least 50% biology in the final two years of study, you are eligible to apply for associate membership. We recognise this early stage of career development with the award of the post-nominal letters AMRSB. Those who can demonstrate equivalence through other education or training can also apply.

Member (MRSB)

If you are a graduate in a bioscience subject with at least three years’ postgraduate experience (in postgraduate study or in work), you are eligible to apply for full Membership. Those who can demonstrate equivalence through other education or training can also apply.

Any applicant who fulfils the requirements for the AMRSB grade of membership and has completed 2 years of Continuing Professional Development (CPD), resulting in their being awarded at least 50 credits per year through the Royal Society of Biology CPD scheme are also eligible.

Note: Any years spent undertaking full-time postgraduate study (within the biosciences, including teaching qualifications) can be included as experience towards gaining the member (MRSB) grade. For example 1 year of full time study is equivalent to 1 year of experience, and 2 years of part-time study is the equivalent to 1 year of experience.
