Get Certified

AALSO offers a multi-level operator competency acknowledgement program based on exams created and administered by the AALSO Certification Committee.

AALSO believes that it is appropriate to develop recognition criteria and a proficiency program that encourages Zoo and Aquarium institutions to incorporate these training criteria into their operator development program.

Previous Symposiums & Events

I very much lacked hands-on experience in life support and AALSO provided me that experience in plentiful amounts. The certification exams were an additional bonus that greatly aids my own professional development.

Workshops were AMAZING. It is one thing to read white papers and look at tech sheets but it’s another thing to be able to do it. The only wish I have is to have more time to do more workshops

Really appreciated the “choose your own adventure” pacing of the conference.  I felt like I had the opportunity to shape my week’s schedule in a way that best suited what I needed versus getting stuck in one track.  Offering the hands-on workshops multiple times through the week was appreciated.
