Their email update from March 25 -- bolding as in the original.
The cited study "Using Stanford University’s Education Program for Gifted Youth (EPGY) to Support and Advance Student Achievement" is at http://steinhardt.nyu.edu/scmsAdmin/media/users/ra977/EPGY_Report.pdf .

Dear XXX,
As promised, we wanted to provide an update on the evolution of EPGY and our progress on the next generation of the program.
One of the most critical elements of a child’s education is the vision and dedication of the parents. Your support, feedback and continued involvement in the program have been instrumental to our success.
Since December, the EPGY and Stanford teams have heard from many of you about how we can make EPGY even better. In our last communication, we outlined three specific focus areas:
Evolving the educational technology
Incorporating additional instructional strategies
Opening the lines of communication with you and your kids
To begin addressing those issues, we convened some of the foremost thinkers and experts at the intersection of education and technology. Our collective efforts are leading to changes that are already taking place. You and your student may have noticed the updated EPGY website, for example, which is just the first step in upgrades to the site design, content and functionality.
You may have already seen upgrades to the EPGY program technology as well. The first set of upgrades will be rolling out over the next few months – we’re particularly excited to move the K-7 Mathematics, Language Arts & Writing, and Beginning Algebra courses to a modern HTML5 platform, which will enable tablet and mobile accessibility.
Over the next few months, we will continue to work with our new partners to develop and implement specific plans for the next generation of the EPGY program – aimed at maintaining its efficacy while modernizing its technology. You may see invitations to participate in the process by providing feedback on your experience with EPGY via surveys and focus groups. Your input remains critical to our program’s success.
Finally, we are excited to share the results of a recent independent evaluation of EPGY’s effectiveness by New York University’s Steinhardt School of Culture, Education and Human Development. In reviewing and analyzing more than 10 years of student performance data, this study concludes that “access to a tool like EPGY will significantly enhance the ability of parents and educators to meet the learning needs of a broad range of students.”
We look forward to hearing from you and sharing more in the coming months. Until then, please don’t hesitate to reply to this email with any questions, concerns or additional feedback.
Sincerely,
The EPGY Team, Stanford University
