The following was submitted by WGBH

Academic teams from 95 public high schools across Massachusetts will gather at WGBH in Brighton on November 4 for a chance to compete on season four of High School Quiz Show. Hosted by Billy Costa, the Emmy Award-winning, fast-paced game show showcases teens from across the Commonwealth and celebrates academic achievement.

See the full list of schools here.

On “Super Sunday,” each academic team of four students will take an identical oral quiz of 100 questions. From the 95 schools, the top 16 teams will advance to appear on the televised show, a single-elimination, bracketed academic tournament that includes eight qualifying matches, quarterfinals, semifinals and a state championship match.

This year the season will culminate with a Bay State vs. Granite State showdown, when WGBH’s High School Quiz Show state champion team meets New Hampshire Public Television’s Granite State Challenge “SuperChallenge” winner for the very first inter-state quiz show play-off.

“It was our hope to create a showcase for academic achievement that would eventually take hold in communities across the Commonwealth,” said Executive Producer Hillary Wells. “By all accounts, it looks like we’re well on our way with a record number of registered schools for this year’s Super Sunday, audience growth year after year, and increasing social media banter and buzz. The real credit, of course, goes to the coaches and to the participating students who continue to impress and amaze us with their enthusiasm, poise under pressure, and depth of knowledge.

All questions on High School Quiz Show are aligned with the Massachusetts high school curriculum standards in subjects including literature, history, science, and math, as well as current events and general knowledge. The weekly series begins taping at WGBH in January in front of a live studio audience.

High School Quiz Show is endorsed by the Massachusetts Department of Elementary and Secondary Education. The Princeton Review judges the televised competition and reviews the questions.

Major sponsorship for High School Quiz Show is provided by Safety Insurance and the Bank of America Charitable Foundation.

Additional funding is provided by Massachusetts Teachers Association, XFINITY from Comcast, Harvard Summer School Secondary School Program, Bentley University, Subaru of New England, and Brain Injury Association of Massachusetts.

The Middlesex District Attorney’s Office and the non-profit organization Team Impact are getting together on an effort to benefit kids facing life-threatening illnesses by partnering them with college athletes, according to the district attorney's office.

Team Impact pairs these children with college athletic teams to provide the child with a team-based support system during their treatment and beyond, according to Leone's office.

The collaboration, which is sponsored by the district attorney's office, will use Leone's existing relationship with the Middlesex College Consortium to recruit schools to participate in Team Impact's program.

The consortium, established in 2007, created bi-annual meetings with Middlesex County college and university safety officials to focus on the unique safety and security issues on their campuses. Representatives from schools’ administrations, as well as campus safety and security staff leaders, partner with the district attorney's office on prevention efforts aimed at keeping campuses safe.

“By focusing on prevention through partnerships like these, we hope to make a positive and lasting impact on young people so that they can make constructive and healthy decisions for their future," said District Attorney Gerry Leone in a prepared statement.

Dan Walsh, executive director of Team Impact, said he is thrilled about the new partnership with Leone's office.

“Initially, this collaboration will boost our family and athletic outreach efforts across Middlesex County communities and the 26 colleges within them," Walsh said in the statement.

In future phases, Team Impact plans to broaden its mission and the population of children they serve, and to work with Leone to identify kids who would benefit most from their program.

The collaboration will eventually include establishing a referral process in which children facing adversity, such as child survivors of crime, children whose family members have been victimized, and at-risk youth, are also partnered with local athletes, according to the statement.

In return, the athletes participating in the program create a positive experience for a youth facing incredible life challenges.

Middlesex County is the largest county in Massachusetts and one of the largest counties in the country with 54 towns and cities and 26 colleges in urban, suburban, and rural areas, comprising over one quarter of the population of Massachusetts.

The Middlesex District Attorney’s Office has offices throughout the county, including communities such as Ayer, Cambridge, Concord, Framingham, Lowell, Malden, Marlborough, Natick, Newton, Somerville, Waltham and Woburn.
