The Lower Elementary is part of the Elementary School, and serves children ages six to nine years in multi-age classrooms that include the first through third levels/grades. This multi-age year cycle allows the teacher to develop a deep understanding of each student, and creates the opportunity to provide a comprehensive, individualized education for each child.  In addition, mixed-age classrooms provide advanced academic models for younger students, and offers older students opportunities to lead by example.

In the Lower Elementary classrooms, St. Alcuin students begin to address more complex problems, no longer content to simply ask "what," but curious about the "how" and "why" of problems. The academic focus is advanced and adjusted to embrace abstract thinking, the next important step in their lives.  This environment is the launching point for interactive, interdisciplinary group work.  With an emphasis on social responsibility, grace and courtesy, cooperative work is a natural outgrowth of the classroom. These years offer instruction in the areas of language development, mathematics/geometry, Spanish, history, world geography, botany, zoology, physical education and the visual and performing arts. Technology is also integrated into the curriculum using computers in the classroom.

Standardized testing is begun in the third year of the program.
