The document is a letter from Vivian Lu, PR Representative of SinaTab, to Rita Braver at CBS News. It summarizes that the U.S. Department of Education named SinaTab as the brand for tablets to use in the Federal Assessment of Educational Progress program, transitioning standardized tests from paper to electronic format. It notes that students in low-income areas previously had limited access to the program. SinaTab plans to donate 20,000 tablets to improve access and performance. The CEO of SinaTab and FAEP program chief officer are available for interviews next week to discuss SinaTab's role and the benefits of the technology-based testing system.
