postscreening

Postscreening is the stage or set of processes that follow an initial screening. It involves additional evaluation, verification, or data refinement intended to confirm eligibility, improve accuracy, and reduce the risk of incorrect decisions based on early screening results.

In clinical research, postscreening often occurs after preliminary eligibility screening to confirm that participants meet all inclusion and exclusion criteria. It may include re-consent verification, health status updates, laboratory checks, or consent reaffirmation before enrollment or randomization.

In employment or education recruitment, postscreening refers to steps taken after resume screening, such as structured interviews, reference checks, background investigations, or skills assessments to validate qualifications and fit.

In security, postscreening can refer to secondary checks following an initial screening at access points, such as identity verification, credential validation, or risk assessment interviews.

Practical considerations include that postscreening adds time and cost, can delay decision-making, and may raise privacy concerns. It requires clear criteria and documentation to ensure consistency and fairness.
