Non-Animal Care Internship Descriptions and Requirements

The Houston Zoo offers Veterinary Conservation Research Internships each summer in Avian Conservation, Amphibian Conservation, and EEHV. Applicants MUST have successfully completed at least one year of education at an accredited veterinary college by May 2019 to be eligible. Candidates should have a passion for zoo or wildlife medicine and an interest in research and scientific writing. Internships are unpaid.

The Veterinary Conservation Research Interns will work closely with Houston Zoo veterinarians as well as husbandry and conservation specialists, and have hands on experience caring for endangered birds, amphibians, and others relevant species.

Research internships will follow the same expectations and application fees as General Internships as referenced above. Apply by the timeline indicated.

Vet Student Research Internship Descriptions

General Internship Requirements

Age and field of study

  • At least 18 years old as of the internship application due date and currently enrolled in college (or within 1 year of post-college graduation at application due date)
  • Applicants should be studying a field related to the desired placement

Background Check

Accepted interns must pass a criminal background check at their own cost of $37, with potential additional fees according to your address history. Background checks for interns that have lived internationally within the last 7 years may also incur separate charges. Due to background check procedures, you must be legally authorized to work in the United States and/or currently reside in the USA.

Additional Background Check Fees

Application and Program Requirements

  • Any applicable university or college credit (or additional requirements) must be arranged by the student through his/her institution and presented to Zoo staff during interviews
  • All applicants must provide a cover letter, a current resume, and one letter of recommendation from either a professor or previous employer in their online application
  • Interns are required to provide proof of a negative TB test (valid for the duration of the internship)
  • Minimum time commitment is 200 hours but may be as high as 400 hours – specific hours vary by department (please review department requirements in the description documents above for animal care, non-animal care, or vet research programs)
  • Give a 15 minute final presentation for their department

Things to Know

  • T-shirts and name tags will be an additional $30 cost to you. This is in addition to your background check costs.
  • All housing and transportation must be arranged by the intern
  • Completion of an internship does not guarantee full-time or part-time job placement at the Houston Zoo
  • Most internships are unpaid as they are designed to mimic academic training. Those sections that offer stipends are indicated within the internship description documents. Paid internships are occasionally offered depending on funding; visit the Houston Zoo Careers page for any available paid opportunities.

What Makes a Qualified Applicant

Internships at the Houston Zoo are designed to be educational experiences, but you should have an academic or professional background to some extent in the area that you want your internship. To be most competitive as an animal care intern, you should get experience working with animals in other capacities (animal shelters, wildlife rehabilitation clinics, or large animal work for example).

Going above and beyond the classroom setting will prove your passion for this field! Seek extra-curricular experiences that will showcase your ability to work on concepts related to the focus of your desired internship.

If your skill set does not lend itself to the internship you want, be sure to explain fully why you are the best candidate in your cover letter. Work ethic, the ability to get along with others, utilizing good judgement, and enthusiasm for conservation are valuable skills that are not career-specific.
