From the Data Forensics panel presentation: Most of the states are using data forensics results to back up their feelings for further investigations in a school district. #COTS2019
#COTS2020 retweeted
But, can we detect cheating by data forensics?
Steve Addicott said no to that: “Data forensics can't detect cheating, it gives us a red flag about something abnormal going on”. #COTS2019
