AO1

AO1 is an acronym used in several different fields, but it is most commonly associated with educational assessment in the United Kingdom. In this context, AO1 refers to the first assessment objective in marking schemes, typically focusing on knowledge and understanding of the subject content. It is used to gauge a student’s recall of facts, definitions, concepts, and procedures, as opposed to higher-order skills such as analysis or evaluation.

The exact wording and scope of AO1 vary by subject and by examination board. While some boards emphasize basic recall and comprehension, others may specify that AO1 involves presenting accurate information in an appropriate form and with sufficient accuracy. In many qualifications, AO1 is complemented by additional objectives (for example AO2, AO3, AO4) that assess different cognitive skills such as application, analysis, synthesis, and evaluation. The relative weighting of AO1 compared with other objectives can differ across subjects and qualification levels, influencing how students allocate their study effort.

Beyond education, the acronym AO1 may appear as a code, label, or abbreviation in other organizations and projects, where its meaning is context-dependent. Because AO1 is not universally standardized, its interpretation should be drawn from the specific context, such as a syllabus, marking rubric, project documentation, or glossary provided by the relevant organization. When in doubt, consulting the official documentation is recommended to determine the intended meaning of AO1 in that setting.
