We can understand why some people might be concerned that wearing headphones is unacceptable – knowing that you are being monitored on webcam, one might worry about how one looks, or even if the test invigilators think that someone could be speaking to you through the headphones. However, you are allowed to wear headphones / earphones while you sit the test. This should be reassuring to those that are not able to sit the test in a quiet room at home, or don’t have a fast internet connection at home – it means that sitting the test in a busy space like a public library is perfectly possible.
From CASPer’s site, we are told the following: ‘You may use headphones to help you concentrate and/or eliminate background noise. For your test, you will need access to a computer, webcam, and reliable internet connection.’
To confirm the above, we can also look to the following statement from the CASPer team: ‘in order for you to successfully complete the online CASPer test, you will need a computer with a stable internet connection, keyboard, audio output (Speakers or Headphones), and a webcam.’
