<p> Aim To compare the clinical practice experiences of seconded healthcare assistants (HCAs) with four major socialisation concepts.</p> <p> Method The sample was comprised of eight seconded HCAs, all from the same pre-registration mental health nursing cohort. A semi-structured focus group strategy was used, with the group convening on a yearly basis.</p> <p> Findings The practice learning experiences of seconded HCAs are different to other nursing students and could be viewed as a unique socialisation process.</p> <p> Conclusion: Course planning teams should consider socialisation factors and supportive mentor strategies when designing the first year of pre-registration nursing programmes.</p>
