A secondary field in Chemistry gives students a well-rounded experience of the discipline. This secondary field is appropriate for anyone who has an inherent interest in the subject or would like to gain a deeper knowledge of science to use in their professional lives.

REQUIREMENTS: 6 courses (24 credits)

Six letter-graded courses in chemistry that include at least one upper level course in chemistry. Upper-level, letter-graded courses in chemistry include Chemistry 40, 60, and any 100- or 200-level chemistry course.


Students completing a secondary field in Chemistry must earn a C- or better in each of these courses, with the exception of designated Freshman Seminars, which are graded SAT/UNS.

Most students interested in the secondary field will take four or five of the following introductory courses: Life and Physical Sciences A, Life Science 1a, Physical Sciences 1, Chemistry 17, Chemistry 20, Chemistry 27, and Chemistry 30. However, students choosing to complete a secondary field in Chemistry will be free to choose any six courses in chemistry as long as one of these courses is an upper-level course in chemistry.

One term of research for credit via the courses Chemistry 91r, 98r or 99r may be counted towards the secondary field requirements. These courses do not satisfy the upper-level course requirement.

The Harvard Summer School courses Chemistry S-1 a, b and Chemistry S-20 a, b can be used to complete secondary field requirements with each counted as one year-long course (two 4-credit courses) in chemistry.

Any Freshman Seminar or General Education course offered by a member of the Department of Chemistry and Chemical Biology (e.g., FS 22J) may be used to count towards a secondary field in Chemistry, if at least two upper-level courses in chemistry are included as a part of the six required courses.

One course taken abroad may count toward a secondary field in Chemistry if successfully approved by petition to either the Director of Undergraduate Studies.

The sophomore tutorial in Chemistry, offered in the spring term, is optional and cannot be taken for credit by any student. Secondary field students may participate in the sophomore tutorial regardless of class year.


Students who notify the department of their intent to pursue a secondary field will be included on the Chemistry concentrator email list and will be welcome at all undergraduate social and academic events including the sophomore tutorial. Once a student has chosen a secondary field in Chemistry, the student should contact the Director of Undergraduate Studies, Dr. Gregg Tucci (, for advising. Priority for appointments with the DUS will be given to concentrators during shopping period.
