Voters are beginning to size up Sen. Joseph R. Biden Jr., who accepted the Democratic nomination for vice president last night at the party’s convention in Denver.

But more than a dozen students at Delaware Technical and Community College have already had their say about Mr. Biden’s wife, Jill, who teaches English at the college’s Stanton/Wilmington campus. And their conclusions, on the Rate My Professors Web site, are generally good.

Mrs. Biden’s overall rating is 3.6 on a scale of 1 to 5, with 11 of 16 responses ranking her as a “Good Quality” instructor.

Her lowest grade was in “Average Easiness,” where respondents gave her a 2.9 out of 5. Her grades for clarity and helpfulness matched her overall rating.
