Available Certification Exams

Order-Level Exam (Citizen Science Exam)

The order-level exam includes aquatic insects and noninsects with image collages drawn at random from a bank of images. The exam is a 20-question, multiple-choice, timed 45-minute exam. The exam is an honor code, non-open notes exam. When payment is received, the exam coordinator will email an access code for the exam from tcp@stroudcenter.org within 3-5 business days. Once the access code is received the candidate can take the exam at any time. The exam will be scored immediately after completion. Upon certification, a digital certificate will be available for download. Those wishing to be listed as certified taxonomists will need to reply back to tcp@stroudcenter.org with the correct information.

Family-Level Exam

The family-level exam includes aquatic insects only with image collages drawn at random from a bank of images. There is a family-level practice quiz available here.

Genus-Level Exams

Four genus-level exams are available:

  • Group 1: General arthropods (specimens), East and West* testing. Genera of Crustacea and arthropods other than Ephemeroptera, Plecoptera, and Trichoptera (EPT, see Group 2) and Chironomidae (see Group 3). Immatures and adults as appropriate.
  • Group 2: EPT (images), East and West* testing. EPT genera (nymphs and larvae only).
  • Group 3: Chironomidae (images)**, North American. Chironomidae genera (larvae only).
  • Group 4: Oligochaeta (slides)**, only North American genera.
  • Group 6: Diatoms

*“Eastern” genera will be those occurring east of the Rocky Mountains and “Western” genera will be those occurring in and west of the Rocky Mountains. It should be noted that geographic and phylogenetic coverage of this examination may be modified as testing protocols are improved. Candidates should be prepared to identify genera from throughout the examination region.

**Chironomidae and Oligochaeta exams are not divided into Eastern and Western genera.

Registering for an Exam
