After our successful HS Programming Contests held in 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, and 2022, we are excited to invite to this year's contest. As in past years, this contest will be held online. Anyone enrolled in a high school (or middle school) is eligible to participate however, you will need a teacher (or parent volunteer) functioning as the official team coach or sponsor. Please see below for details of the rules.

Please share this event with your friends and colleagues at other schools! Capacity permitting, this event is open to all high schools in the United States and possibly beyond, although we hope to particularly attract schools from the midatlantic region.


Based on the feedback we have received from coaches and contestants, we will hold this year's contest using the traditional format of an ICPC contest, with teams of (up to) 3 students sharing a computer to solve as many problems as possible within 5 hours.

A coach needs to register each team. We ask that the coach is also the person that can testify that the team obeyed the contest rules.

We anticipate that there will be widely varying levels of skills and accordingly, the problems will require varying levels of skill. We will include problems that require only simple I/O, control structures such as if/else and/or loops, as well as problems that require basic algorithms. To skillfully participate in a contest such as this one, participants need to quickly triage problems and solve the easiest ones first.

All problems will involve reading input line by line from standard input, and outputting an answer to standard output. (No other file I/O is allowed.) Coaches should make sure that contestants are familiar with this style of I/O. This may require the use of java.util.Scanner or similar classes in Java or raw_input() or sys.stdin or similar in Python.


The problem sets from 2014-2020 are now available on Kattis! (2014, 2015, 2016, 2017, 2018, 2019, 2020). You can practice problems individually, but you can also create a contest with these problems (if you haven't done them already).



Sat, Dec 9, 2023. 11:00pm-5pm EST. Registration will close before the contest.
