The New England First Amendment Coalition recently launched a monthly educational series featuring short, practical lessons on journalism and the First Amendment.

The goal of the program — called “30 Minute Skills” — is to provide reporters and other citizens knowledge they can use immediately in newsgathering, data collection, storytelling and other areas of journalism and First Amendment law.

The lessons will be provided in a 30-minute format to accommodate the demanding schedules faced by many working in New England newsrooms.

The program is free and open to the public. Registration for each lesson is required.
