Happening once each school term. A British school year is usually cut into three terms, so a 'termly report' arrives three times a year, and a 'termly meeting' happens three times a year. The word works two ways, and the form does not change. As an adjective it sits before a noun: 'a termly newsletter', 'the termly fee', 'termly assessments'. As an adverb it comes after the verb: 'Parents are invited in termly.' 'The committee meets termly.' It fits the same family as 'daily', 'weekly', 'monthly', 'yearly' — all of them do this double job. It is a narrow, institutional word. You meet it in letters from schools, in university handbooks, in fee schedules — the language of an office writing to parents or students. People almost never say it in conversation; a parent would say 'we get a report every term'. It is also strongly British, because it depends on the British three-term year. In America, universities run on semesters and would say 'each semester'. So: understand it when a school writes it to you, and use it if you are writing that kind of letter yourself. Otherwise 'every term' is the natural thing to say.

每學期一次的（英式學制一學年三學期）。台灣一學年是兩個學期，所以沒有完全對應的字，日常會說「每學期」「一學期一次」。學校公文裡的 termly report 就是「每學期的成績單／報告」。
