It is possible that you will encounter this issue more often when using the InCAS primary assessment. This is because the InCAS assessment is media heavy, more so in some sections than others. Therefore, you may notice that you have had no problems when using other CEM assessments but that certain sections of InCAS are affected.
We recommend the web-only version for schools that have a reliable, high-speed internet connection. You will typically be able to assess one pupil for every 1Mbps of line speed, but this can vary depending on other factors within your school.
We recommend you try the following:
- Assess students in smaller groups.
- Stagger the start times for students. A large group of students launching the assessment at the same time may cause local bandwidth problems.
- Advise students to not click their name in the candidate list or submit details on the free entry screen (CABT for MidYIS, Yellis and Alis/CEM IBE), or enter their password (InCAS and UKiset) at the same time.
- Run the assessments on devices with wired Ethernet connections rather than WiFi.
If your school does not have a constant internet connection, has a very unreliable connection, or you wish to test a higher number of pupils at the same time, we recommend using the non-web version. There is no limit to the number of pupils you can assess at the same time using the non-web version. All content is stored locally on your school’s server or computer, and you will need to return the results manually to CEM after the students complete their assessments.
