The Houston Zoo invites college students and aspiring professionals to participate in unpaid internships at our AZA accredited facility.

Internships are available in most animal sections, as well as conservation, education, marketing, special events, and water quality departments. Internships are designed around spring, summer, and fall semesters, but not all areas will have openings available during each term.

Be sure to check out our Collegiate Conservation Program internship offered each summer, described below!

There are a few types of Internships

Non Animal Care Internship Descriptions and Requirements

The Houston Zoo offers Veterinary Conservation Research Internships, one in Avian Conservation and one in Amphibian Conservation. 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.

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 and amphibians.

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

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 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

Program Requirements

  • 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 document below)
  • Give a 15 minute final presentation for their department

Things to Remember

  • T-shirts and name tags will be an additional $20 cost to you
  • All housing and transportation must be arranged by the intern
  • Certain Animal Care interns are required to provide proof of a negative TB test (valid for the duration of the internship)
  • Note that completion of an internship does not guarantee full-time or part-time job placement at the Houston Zoo

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.
