Makyun is from the Philippines and there, batch is synonymous with graduating class (and is even preferred to the word class). So it's a regional thing.

The original kanji 期 is a "time period", but if it's used as a counter, then it refers to a "class", a "term" or a "session" (of Parliament, for example). In this context, it seems to refer to the the term when an investigator joined CCG (where terms are from April 1st to March 31st, if we assume that it matches the Japanese fiscal year/academic year). But I don't know a good English word to describe that.

The only thing that's certain: Imperial's translation "semester" is no good, since the period it refers to is one year.
