iClicker Student app


COVID-19 and the switch to remote teaching has necessitated a change in the way classroom polling is conducted at JHU. Starting in the Fall 2020 semester, we will no longer use physical iClickers and will transition the iClicker Student polling app (formerly known as iClicker REEF). This page provides information for students on how to successfully implement the iClicker Student app from Fall 2020 onward.


The iClicker Student app (formerly known as iClicker REEF Polling system) is an in-class voting system that allows students to user their phones, tablets, or laptop/desktop computers to participate in real-time voting during class. For now, information for faculty is being directly communicated. If you are faculty in KSAS/WSE and are interested in using the iClicker Student app, please contact

Students - Getting Started

Setting up and using iClicker Student app is easy and can be summarized in a few steps:

  • If you're using a phone or tablet to vote, download the app
  • If you don't already have one, create a student account on iClicker (app or browser) (only one account needed)
  • Login to iClicker Student app via the mobile app or through the browser
  • Find your classes and add yourself to those classes
  • Purchase a subscription (new accounts can vote for 2 weeks, then a subscription is required)
  • Join your class when it's running and vote!

Here are some detailed instructions from iClicker.

JHU Specific Notes

You only need one iClicker student account. If you think you might already have one, check using the iClicker password reset.

If you are setting up an account for the first time, you should use the same email address that is used by Blackboard. What is this address? It's usually your, unless you have changed your email in SIS. You can tell for sure by logging into then clicking on your name in the upper right and choosing Settings > Personal Information > Edit Personal Information.

You should also use your JHED ID (with no other information) in the last field (JHED ID). Do not use or your student ID. JHED IDs look like jhopkin1, not like 4RGL38 (which is a student ID). Here's a graphic for reference.

iClicker REEF Polling Student Account Setup

After you've logged in with an existing account, add your Fall Courses that are using iClicker. You can search by course name, faculty name, or course number.


Purchasing a subscription will be required. New iClicker accounts may participate in voting for 2 weeks for no charge. You can use this time to make sure your account is working correctly. After 2 weeks, you will need to purchase a subscription to continue voting. You can do this in the app or on

For refence, the plan is to use iClicker Student app from Fall 2020 on. If you think you will only need it this one semester, purchase the 6-month subscription. For first-year students, it makes sense to purchase a 1-2 year plan (or greater), since there is some savings and you will probably use it in Spring 2021 and later.


The most common student issues are:

  • duplicate acocunts,
  • wrong email,
  • or wrong JHED ID.

Please read the instructions above carefully and edit your iClicker Account Profile if needed to make sure you get credit for all your votes. If your instructor tells you that your iClicker account is not synchronizing with Blackboard, you may need to update your email or JHED, here's a quick guide on iClicker Roster & Grade Sync Integration.

New Features

Unlike the old physical clicker system, iClicker Student app allows you to review your voting history in detail.

You can also create your own study tools based on questions asked during class.
