Certificate Programs

Humane Sciences and Toxicology Policy Certificate

Sponsoring Department
Environmental Health Sciences


The Certificate Program will introduce, and explain the application of, the “3Rs,” (reduction, replacement and refinement), which are the guiding principles of humane science as well as demonstrate how the use of humane science principles in biomedical research can lead to more robust scientific methodology and knowledge. The Program course of study covers the scientific principles needed to appreciate humane science and identify and evaluate its implications in biomedical research and public health policy. Persons completing the certificate will be well equipped to translate new toxicological knowledge into scientifically credible product safety evaluations and hazard assessments and apply these concepts to environmental health decision making.

Educational Objectives

The educational objectives of this Certificate Program are:

1.) To provide students with an understanding of the principles that govern the relationship between biomedical researchers and laboratory animals;
2.) To demonstrate the application of transgenic, in-vitro, computational, non-mammalian and non-animal research in toxicology;
3.) To illustrate the ways in which humane science and alternatives are used in setting regulatory standards and making environmental health policy decisions.

Intended Audience

The certificate program is open to persons who hold undergraduate or graduate degrees in public health or the biomedical sciences. It is also open to any student in a degree-granting program at the University, although it is anticipated that most enrollees will be students at the Bloomberg School of Public Health. Persons who are members of Institutional Animal Care and Use Committees (IACUC) and/or involved in animal welfare issues are encouraged to participate in this certificate program.

Admissions Criteria

It is recommended that students planning to pursue the Certificate contact the Department as soon as possible. All students pursuing the Certificate must contact the Department no later than the first week of the term in which the final course is to be taken.

Non-Degree Students: A student not enrolled in a degree program at the Johns Hopkins Bloomberg School of Public health must have an undergraduate degree from an accredited college or university. Any student may register and complete the certificate program as a Special Student Limited; however, such students may pursue courses in only one certificate in the School. Admission to the Department as a Special Student Regular or degree candidate is required for individuals wishing to enroll in coursework beyond that required by the Certificate Program.

Degree Students: Degree-seeking students at the Johns Hopkins Bloomberg School of Public Health: Students in a masters or doctoral program at the school can enroll in the Certificate Program as part of their training.

Course of Study

The Certificate curriculum consists of the successful completion of six courses that provide essential public health knowledge and skills, as well as address critical issues in humane sciences, examine the 3Rs in biomedical research, enhance knowledge about experimental design and analysis, and study the translational and policy implications of humane sciences.

Gainful Employment Program Information

In accordance with US Department of Education regulations, the JHU Bloomberg School of Public Health is required to disclose graduation rate data, median loan debt data, and other select information for all Title IV eligible gainful employment programs. To see the most recent data available for this gainful employment program, please view the attached disclosure.

Note: Fewer than 10 students graduated from this program in the 2012-13 academic year. Therefore, in accordance with US Department of Education guidelines on student privacy, the on-time completion rate and median loan debt data are not published.  The restrictions imposed by the current US Department of Education online disclosure form limit the number of jobs related to this program that can be displayed in this disclosure: the job(s) listed here represent only a sample of the jobs related to the program.

  1. The certificate is offered to Johns Hopkins University graduate and post-doctoral students (including physicians completing residency or fellowship programs) who are interested in adolescent health.
  2. The certificate program length is flexible; it varies from student to student, however, the certificate must be completed within three years.  Students do not need to be enrolled in a certificate course during consecutive terms.  The number of certificate course credits taken may range from zero to 22 per term.  Degree students earn the certificate simultaneously with their degree program and determine the number of credits taken each term with advisor approval.  Full-time degree students are able to complete the certificate within one academic year.
  3. Tuition, application fee, and book costs are subject to change from one academic year to another academic year.
  4. Completion rates will be tracked beginning in academic year 2012-2013.
  5. The Council of Public Health Education which accredits schools of public health does not require schools to track job placement rates for certificate programs.
