Andy Brady found school-spider:

• Slightly increases student collaboration“We choose not to make use of such functionality so it's unfair to judge.”
• Moderately reduces teacher workload“Updating school website is easy and fast and encourages staff to take ownership and post recent material.”
• Slightly improves school processes“Again, we have yet to use these tools - such as the text services, parent evening appointments etc... but I am sure most schools find these tools extremely useful!”
• Moderately saves school money“Value for money of the quality of the service and product is excellent. The referral scheme also offers a valuable incentive to spread the word.”
• Significantly improves parent engagement“Being able to share information and pupils work, along with tutorial videos and documentation helps to engage our parents.”
