WASHINGTON, Feb. 24 — Internal Justice Department performance reports for six of the eight United States attorneys who have been dismissed in recent months rated them “well regarded,” “capable” or “very competent,” a review of the evaluations shows.

The performance reviews, known as Evaluations and Review Staff Reports, show that the ousted prosecutors were routinely praised for playing a leadership role with other law enforcement agencies in their jurisdictions.

The reviews, each of them 6 to 12 pages long, were carried out by Justice Department officials from 2003 to 2006. Each report was based on extensive interviews, conducted over several days with judges, other federal law enforcement agencies and staff members in each office.

It had been known that the reports were mostly favorable, but the reports themselves had not been made public.
