National Biology Bee
Varsity & Junior Varsity Divisions
New for the 2025-2026 Academic Year!


National Biology Bee Varsity & Junior Varsity Divisions Overview

The National Biology Bee is a quiz competition for individual students, testing knowledge of all aspects of biology at a grade-appropriate level. For students competing in the Varsity or Junior Varsity Division, the National Biology Bee consists of two stages. The first is a 50 question multiple-choice National Qualifying Exam. The second stage is the National Championships, which will take place online on Sunday, May 17, 2026 (preliminary rounds) and Tuesday, May 19, 2026 (playoff rounds). The National Championships is entirely a buzzer-based quiz competition. Please note that the National Biology Bee is a distinct competition from the National Science Bee. Questions in the National Biology Bee focus exclusively on biology. Questions in the National Science Bee focus on both biology and other aspects of science.

Competition Format
For students competing in the Varsity & Junior Varsity Divisions, the National Biology Bee is a two-stage competition, consisting of the National Qualifying Exams and the National Championships. Students can also qualify for the International Science Championships and the International Environmental Science Olympiad by competing in the National Biology Bee.
1
National Qualifying Exam
For the Varsity and Junior Varsity Divisions, students first compete in the Qualifying Stage through the National Qualifying Exam. For these divisions, the National Qualifying Exam is a 50 question multiple choice exam. All questions have 4 possible answer choices. The National Qualifying Exams are scored on the basis of 2 points for a correct answer, 0 for a question left unanswered, and -1 point for an incorrect answer. This scoring system rewards partial knowledge but not random lucky guesses. Students who have no clue about a particular question should thus leave it unanswered, but if they can narrow down the answer choices, they should likely then take their best guess even if they are not 100% sure.
Students qualify for Nationals through the National Qualifying Exams in one of three ways.
Students may take the National Biology Bee National Qualifying Exam online, at all in-person National History Bee and Bowl Regional Tournaments during the lunch break, at all in-person National Science, History and Geography Bees, or at select all-subject quiz bowl tournaments that are not run by International Academic Competitions. There are three versions of the National Qualifying Exam, which are known as Set A, Set B, and Set C. For National Qualifying Exams that are offered at National History Bee and Bowl tournaments, the Exam Set corresponds to the question set that the tournament is using. If the Exams are taken at National Science, History and Geography Bee regional tournaments, then if the tournament is run on Red Set, the Set C exam version is offered. If the tournament is run on White Set, the Set B exam version is offered. If the tournament is run on Blue Set, the Set A exam version is offered. If the tournament is run on Gold Set, then typically the Set C exam version is offered, though IAC may contact students to see if they prefer to take the Set B or Set A versions instead.
For the National Biology Bee, the questions on all three versions of the National Qualifying Exams follow the National Qualifying Exam Question Distribution.
If taking the National Biology Bee National Qualifying Exam online, students have a 20 minute time limit.
If taking the National Biology Bee National Qualifying Exam at an in-person National History Bee and Bowl tournament, students may also take the National Qualifying Exams for the National Geography Bee / US Geography Championships / US Geography Bee (one exam is used for all 3 of these competitions), National Humanities Bee, National Political Science Bee, US History Bee, and National Science Bee. If a student takes just one exam, they have 20 minutes. If a student takes two exams, they have 40 minutes, but if they take three, four, five, or six exams, they still only have 40 minutes (as time is limited during the lunch break of a tournament).
If taking the National Biology Bee National Qualifying Exam at an in-person National Science, History, and Geography Bee tournament, students may also take the other five National Qualifying Exams as listed in the above paragraph. At these tournaments, National Qualifying Exams are not timed on an exam-by-exam basis, but rather, students can take them in the designated Exam Room whenever it is open. Students cannot leave the Exam Room and come back to an exam that they had previously started. Students should be mindful of their schedule for the day and plan the times when they wish to take exams accordingly.
Students qualify for Nationals through the National Qualifying Exams in one of three ways:
- 1
Scoring 75 or higher on any version of the National Qualifying Exam.Scoring 75 or higher on any version of the National Qualifying Exam.
- 2
Scoring among the top 50% of students in one’s age division at an in-person tournament (either a National History Bee and Bowl Regional Tournament or a quiz bowl tournament where the exam is offered). This is inclusive of odd numbers of students and ties for the last qualifying spot. By way of example, if there are 9 students taking the exam, and two students tie for fifth place in the Varsity Division with a score of 63, they would both qualify.
- 3
Scoring at or above the official National Qualifying Score in one’s age division for each exam version. The National Qualifying Scores are calculated for each exam version on the following dates: Set C – December 6, 2025, Set B – February 7, 2026, Set A – March 7, 2026. Thereafter, the National Qualifying Scores do not change even though additional students will take each exam version
Students need only to qualify on any one version of the National Qualifying Exam in any given academic year to be able to compete at the National Championships. If a student qualifies on one version of the Exam, and then takes a different version of the exam but does not qualify on that version, they remain qualified.
The cost is $20 per Exam Version per student.

National Championships
The second stage of the National Biology Bee for the Varsity and Junior Varsity Divisions is the National Championships, which for the 2025-26 academic year will take place online for all age divisions. The preliminary rounds will take place on the late afternoon / evening of Sunday, May 17, 2026. The finals will take place online on Tuesday, May 19, 2026. We hope that you will be able to join us! Varsity and Junior Varsity students will play three preliminary round matches using standard International Academic Competitions buzzer-based online rules with 30 questions each on Sunday. There will then be either one or two playoff rounds which will take place on Tuesday after school. One playoff round will be played if there are 30 students or fewer in an age division; two playoff rounds will be played if there are 31 or more students in an age division. The exact number of students who make the playoffs will be a function of the total number of registrants.
The cost to compete at the 2026 National Biology Bee National Championships is $65. Registration for the National Championships of the National Biology Bee will open in November and run through early May on this page.

International Science Championships &
International Environmental Science Olympiad
Students who compete in the Varsity and Junior Varsity Divisions of the National Biology Bee can qualify for the 2028 International Science Championships and the 2029 International Environmental Science Olympiad which will be held in the summers of those years! In addition to the more common methods of qualifying for these events (by finishing in the top 1/3 of students at any National Science Bee Regional tournament, by finishing in the top 2/3 of students at the National Championships of the National Science Bee, or by scoring 75 or higher on the National Science Bee National Qualifying Exam), students can now also qualify for the 2028 International Science Championships or the 2029 International Environmental Science Olympiad by making the playoffs in their age division at the National Biology Bee National Championships.
Further information on these competitions will be available beginning in 2026. For all questions on these events, please email hs-info@iacompetitions.com.
