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.
Typically, a school will have a bandwidth of 500mb, yet the audio files for the InCAS General Maths module are approximately 45Mb per pupil. This explains why a delay is possible, particularly if assessing a large group of students at the same time.
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 advise you try the following:
1. Stagger the start of the assessment, with smaller groups of students starting a few minutes after one another. This will ease the pressure on your internet and usually solves the problem.
2. Run the non-web only of the assessment. This would easily allow all students to sit the assessment, at the same time, on the same day with no delays.
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.
