Degree Requirements

The following requirements must be fulfilled to successfully complete the Master of Science in Toxicology for Human Risk Assessment.

Coursework & Academic Standards

The curriculum consists of a core of program-required coursework that is taken during the first year of the program. Courses are offered in four 8-week terms from the beginning of September to mid-May. Courses related to the internship and to the capstone essay will be completed in the second year. 

Students must meet minimum satisfactory academic standards to remain in the MS program. To meet this standards, students must:

  1. Maintain a minimum of 2.75 cumulative grade point average
  2. Retake a required course in which they receive a grade of "D" or "F"

If a student receives a grade of "D" or "F" twice in the same required course, they may not repeat the course a third time. If the course is a required core course with no other options, the student will be dismissed from the program.


Students in this professional MS degree program will be expected to assume independent responsibility for a professional project that will be carried out off-site at a governmental agency, nongovernmental organization or industry or private sector company. Specific opportunities will be identified by the student in conjunction with the adviser. The minimum requirements for the internship will be a duration of four months (two academic terms) in conjunction with 32 course credits of special studies and research. The student will be directed in the internship experience by an on-site mentor with whom the adviser will communicate regularly to follow and support the student’s progress and success in achieving the agreed-upon goals of the independent project. If agreeable to the student and sponsor, the overall length of the project period may extend beyond the minimum necessary for completion of the internship requirements of the MS degree program.

Master's Essay and Presentation

Students in professional programs at the Johns Hopkins School of Public Health are required to successfully complete and submit a culminating project that demonstrates integration of the skills developed during the coursework and internship experiences. For students in this program, this project takes the form of an in-depth capstone essay.

The topic of the essay will typically be linked to the specific or general focus of the internship experience and will be chosen in consultation with the adviser, who must approve it. The format of the essay will conform to standards set by the Department and may vary to accommodate the nature of the topic. Students are encouraged to select a topic that will lend itself to publication in a scientific journal. Following approval of the essay, students will make a formal presentation of the essay to departmental faculty and students to complete the requirements for the MS degree.
