The development and dissemination of these systems has been supported through continual federal funding. Thanks to continuing funding from the Institute of Education Sciences, we are able to offer these systems for free. All current finances for the systems are supported by the Department of Education.
Since these systems are made available for research purposes, interested students and teachers are asked to consent to have their data be used for research purposes. Take note that all data is recorded anonymously and that no personally identifiable information can be traced to research data.
