Revision week is a period in the UK and other Commonwealth countries preceding examinations in high schools, higher education institutions, and military colleges. In American colleges, this period is known as a Reading Period. Generally, this period is one week long and free of classes or assessment, permitting students to spend the period revising material, generally in preparation for final exams. With the exception of Canadian post-secondary institutions, is not often allocated for mid-semester or ongoing assessment. Each day of such a period may be referred to as a reading day. The term "revision week" is chiefly used in Commonwealth countries, where it is also known as "swotvac" or "stuvac". For post-secondary institutions in anglophone Canada, it is common to have "reading week" or "mid-term break" during the third week of February, coinciding with Family Day. While in francophone Canada, "semaine d'études," "semaine d'activités libres," or "semaine de lecture," typically falls on the first or second week of March. Some Canadian post-secondary institutions have even adopted reading weeks for the fall academic term, either in October or November, typically coinciding with Thanksgiving or Remembrance Day respectively. In the US this period is generally referred to as reading period or (as slang) dead week or dead days.

Swot as a verb suggests acting like a swot, studying for one's exams. The use of the uncommon and outmoded word 'swot' has led to the backronym Study Week Or Take VACation or Study WithOut Teaching (or Tuition) VACation. There are many other different backronyms that can be derived, and the term stuvac (STUdy VACation, STUdent VACation) is also found. Though once popular and used by universities as the official name for the week, the term seems to have fallen from favour and replaced with study week. As of 2014, however, it is still used by at least three of Australia's Group of 8 universities on the academic calendar. Timing It is scheduled after all the regular class lectures and before final exams. In some universities, reading
