Frequently Asked Questions

All Deerfield math students are expected to have their own graphing calculator and to be proficient in its use.  Any TI-84 graphing calculators is fine, but we recommend the TI‑84 Plus CE which is available for purchase from the school store, Hitchcock House, or online. Teachers are happy to help students learn to use their calculators if necessary.

In order to be eligible for a diploma from Deerfield Academy, students must complete at least Algebra II. Most students choose to take a math class every year, and proceed well beyond the minimum requirement.

New students are sent a placement test in the spring before they enter Deerfield, according to their math record at their previous school. Taking account of each student’s placement score, requested math course, and academic transcript, the math department places students in appropriate classes to match their skill level. Adjustments to levels may be made during the first two weeks of the new term to be sure students are in the class best suited to their abilities.

Before they enter Deerfield, all new students are required to take a math placement test to determine an appropriate class. Students who have already taken a language they wish to continue studying at Deerfield will take a placement test to determine what level class they should take. If the placement in either department is deemed inappropriate after the student arrives, then the teacher may suggest a change of level. Students may also request such a change if they feel they are misplaced. and should consult with their teacher and their academic advisor before contacting the Dean of Studies.
