Data Redaction is the process of masking the data displayed (putting an asterisk * in place of the actual number) to protect student privacy. Different applications may utilize different redaction techniques depending on the tool used, data displayed, and the way the data is combined for display. Each redaction technique has been vetted within the agency and through other groups like PTAC to ensure each application meets the applicable privacy laws and to ensure that student privacy is protected. Two specific examples that handle redaction differently include the Report Cards and the WISEdash Public Portal.
Report Cards: To protect student privacy, data for groups of fewer than 20 students are replaced by asterisks on the public report cards.
WISEdash Public Portal: Learn more about why data for some student groups are not reported on the WISEdash Redaction page. Also, see specific examples below.
