The Minister for Education, Mary Hanafin, has criticised a website which allows students to evaluate their teachers' performance.

Thousands of Irish teachers have been reviewed on the website ''.  Over 11,000 reviews were posted to the site in one day last week.

Mary Hanafin said that when teachers rate their pupils' performance it is done in private.

She said it is entirely inappropriate that teachers' performances should be rated on a website in such a public way.
