Gwinnett school chief Alvin Wilbanks is one of six U.S. superintendents featured in videos about key innovations to emerge from a national initiative to develop highly effective principals.

The two-minute videos of each superintendent highlight new practices to develop leaders and manage career paths, including crafting clear standards for principals and developing strong partnerships with local university preparation programs. Also mentioned: grooming assistant principals, revamping hiring and stepping up support for new principals.

The recommendations were outlined in a report called Building a Stronger Principalship: Districts Taking Charge of the Principal Pipeline, which was released in January and is the third in a six-part series in a multi-year evaluation of The Wallace Foundation's $75-million Principal Pipeline Initiative. Policy Studies Associates and the RAND Corporation are conducting the evaluation.

The videos are being released by the Wallace Foundation, an independent national group dedicated to improving the lives of disadvantaged children. To watch the new videos, click here.
