In response to various numbers of pupils, the Trustees started out by requiring that classes be limited to 40 students as long as there was only one teacher (1811). Later the class size required for one teacher had fallen to 30 pupils, except by special permission of the Board of Trustees (1820) and in 1873 the class sizes were to remain at 30 pupils unless an assistant teacher was employed.

Courses of Study
The Brookeville Academy teachers employed the system of teaching by which the young mind [was] inductively and intellectually led from elementary principles to a comprehension of combinations. Great care [was] taken to avoid anything like rote, also to adapt the studies to the capacities and destination of the pupil. Each recitation [was] attended with analysis and demonstration; and no pupil [was] permitted to leave a text before evincing a thorough knowledge of the subject.(37)

In general the Brookeville Academy started offering basic courses of study which included reading, writing, arithmetic, bookkeeping, surveying, geography, navigation, English grammar and mathematics (1816). Gradually new courses were added such as Latin and Greek (1817); spelling and geography with the use of maps (1818); French and geography with the use of globes (1820); orthography, elocution, instruction in drawing maps, rhetoric, composition, logic, astronomy, natural and moral philosophy, metaphysics and Hebrew (1831); mineralogy, chemistry, botany, Spanish, leveling, gauging, civil engineering, algebra, and conic sections (1834); theoretical and practical agriculture (1849); German, physiology, and geology (1854); practical agricultural chemistry experiments (1856); anatomy (1857); zoology and natural theology (1858)7 and analytical geometry, calculus, and English studied historically (1886).
