Selection Methods - Choosing the Right Tools

Selecting the right people for a role is far harder than it appears, and this video tackles that challenge by examining the core criteria against which any selection method must be judged: validity, reliability, fairness, and practicality. These four standards run throughout the video as a consistent evaluative framework, applied to each method in turn. The discussion is grounded in the AC 2.3 requirement of 5HR02 to weigh the genuine strengths and weaknesses of selection practice rather than simply cataloguing available options.

The video works through a range of specific selection methods, covering application forms and CV screening, structured and unstructured interviews, cognitive ability tests, personality questionnaires, work samples, trial shifts, and assessment centres. Within interviews, the distinction between unstructured and structured formats receives detailed attention, including behavioural and situational questioning techniques and the role of standardised rating criteria. Concepts such as first impression bias, similarity bias, halo effects, adverse impact, and anonymised screening are all named in the context of evaluating how different approaches hold up against the four core criteria. Assessment centres are examined in terms of methodological triangulation across multiple exercises, assessors, and candidates.

Predictive validity is a recurring analytical thread, used to compare methods that range from CV screening at the earliest shortlisting stage through to the resource-intensive design of a full assessment centre. The video also addresses legally defensible selection, the risk of socially desirable responding in personality questionnaires, the test anxiety limitation of cognitive ability testing, and the practical constraints of cost and organisational scale that influence which combination of methods is appropriate in a given context.
