We have been using LanSchool for over 10 years and as it has developed it has become even easier to use and more enhanced with its capabilities. Its Report Server is very useful for monitoring the behaviour of students, which PC's they have used, their internet access and crucially for esafety it helps meet the Ofsted Standards for prevent and other important keyword libraries.
LanSchool is also very easy to setup and customise on a room or class list basis. It does exactly what teachers need in the classroom environment. I.e. disable or limit web access, disable USB, sound, keyboard and mouse access and blank screens with a message. It also lets you login/log off multiple machines as well as power cycle. Lastly, it also has a useful tech console which helps with the network management. This software is relied upon in our busy secondary school environment and I would definitely recommend it for any school
