pretasks

Pretasks are preparatory activities performed before a main task to improve readiness, reduce errors, or gather necessary information. They are designed to lay the groundwork for the primary activity and can vary widely in form and purpose. Pretasks may be formative or summative, depending on whether the goal is to inform future work or to benchmark a participant’s starting point.

In educational settings, pretasks are common as a way to activate prior knowledge, assess readiness, or provide scaffolding. Examples include warm-up questions, pre-reading assignments, diagnostic quizzes, or quick practice problems. They help teachers tailor instruction and students begin the main task with a clearer understanding of expectations.

In professional and project contexts, pretasks appear during planning and setup. Before starting a project task, teams might perform pretasks such as gathering requirements, clarifying goals, aligning on scope, or preparing the working environment. In software development and data projects, pretasks can include environment validation, dependency checks, linting, and data preparation steps that must be completed before core work begins.

In experimental research and psychology, pretasks often serve to familiarize participants with procedures, reduce novelty effects, or collect baseline data. They can include practice trials or training sessions to ensure participants understand tasks and protocols.

Designers of pretasks should clarify the purpose, limit duration and scope, consider potential biases, and ensure inclusion does not disproportionately burden participants. When well designed, pretasks can improve efficiency and data quality, but they add time and resource costs that must be weighed against their benefits.
