Laura Bainbridge found Reading Eggs:

• Moderately reduces teacher workload“It is an activity that can be easily used as part of the guided reading carousel. It is also supporting the progress of children who use it at home and therefore they are becoming more able to read independently meaning less intervention is needed.”
• Moderately reduces attainment gap“For children who use it regularly at home, it is helping them to catch up with their peers in school.”
• Moderately improves teaching efficiency“It cements learning that takes place in school at a pace suitable to the children, meaning less support is needed in school.”
• Moderately improves attainment“Some children love using it at home and I have noticed a big improvement in the ability to segment and blend when reading in school.”
• Moderately builds student knowledge“Children know more phonemes and are becoming more fluent.”
