The Medieval Latin word was widely borrowed (Old French escoler, French écolier, Old High German scuolari, German Schüler). Not common in English before 14c. and the modern use might be a reborrowing. In British English it typically has been restricted to those who attend a school on a scholarship (1510s).

1590s, "of or pertaining to Scholastic theologians" (Churchmen in the Middle Ages whose theology and philosophy was based on Church Fathers and Aristotle), from French scholastique (14c.), from Latin scholasticus "of a school," from Greek skholastikos "enjoying leisure; devoting one's leisure to learning," hence, as a noun, "a scholar," also in a bad sense, "a pedant; a simpleton," from skholē "leisure" (see school (n.1)). Greek scholastēs meant "one who lives at ease."
In English, the meaning "pertaining to or suited to schools or to school education" is from 1640s. As a noun in English from 1640s, "a Schoolman, an adherent of scholasticism, a Christian Aristotelian." Related: Scholastical (early 15c., scolasticalle, "relating to scholasticism;" 1530s in the "relating to a school" sense); scholastically.
It is remarkable that Aristotle, whom the schoolmen placed almost on a level with the Fathers, owes his position entirely to the early heretics ; that the introduction of his philosophy was at first invariably accompanied by an increase of heresy ; and that the Fathers, with scarcely an exception, unequivocally denounced it.

[place of instruction] Middle English scole, from Old English scol, "institution for instruction," from Latin schola "meeting place for teachers and students, place of instruction;" also "learned conversation, debate; lecture; disciples of a teacher, body of followers, sect," also in the older Greek sense of "intermission of work, leisure for learning."
This is from Greek skholē "spare time, leisure, rest, ease; idleness; that in which leisure is employed; learned discussion;" also "a place for lectures, school;" originally "a holding back, a keeping clear," from skhein "to get" (from PIE root *segh- "to hold") + -olē by analogy with bolē "a throw," stolē "outfit," etc.
The basic sense of the Greek word is "leisure," which passed to "otiose discussion" (in Athens or Rome, the favorite or proper use of free time), then it came to be used for the place for such discussion.
The Latin word was widely borrowed (in addition to Old French escole, French école, Spanish escuela, Italian scuola; Old High German scuola, German Schule, Swedish skola, Gaelic sgiol, Welsh ysgol, Russian shkola).

Every living creature has also relations with other living creatures, which may tend to destroy it, or indirectly to aid it, and the various physical forces and conditions exercise their several influences upon it. The study of all these complex relations to time, space, physical forces, other organisms, and to surrounding conditions generally, constitutes the science of hexicology (hexiology?). [Mivart]
