A statement said the 111 people at the ministry for education would also be referred for legal action and quoted the education minister, Majid bin Ali al-Nuaimi, as saying it followed an investigation into "flagrant violations" of rules concerning schools.
Bahrain, a key western ally, has conducted a wide-ranging campaign against opposition groups and political parties since using the army, along with reinforcements from Saudi Arabia and the United Arab Emirates, to clear protesters from the streets. At least 30 people are thought to have been killed.
Among those detained have been doctors who treated the wounded, while opposition newspaper editors have also been told they will be prosecuted for their coverage of the unrest.
On Saturday, the main opposition party, Al-Wefaq, which is predominantly Shia, said a leading lawyer, Mohammed al-Tajer, was also arrested. Mr Tajer had represented Shia activists who had protested at the regime, dominated by the Sunni royal family.
A statement by Human Rights Watch quoted his wife, Huda al-Tajer, as saying masked security officers arrived at their house at 11pm on Friday night, waking their children and searching their rooms.
"My husband hasn't done anything except defend the rights of others," she said. "He is a lawyer. This is his job. He has to have immunity and protection to do his job. I have no idea where he is right now and what they are doing to him. I am really frightened." The government has also threatened to dissolve Al-Wefaq, though a statement confirming it was doing was later revoked.
Sheikh Ali Salman, the party's head, told The Daily Telegraph it was hard to tell what the government's plan was as their actions seemed inexplicable.
"No official notice has reached the society," he said, adding here was a legal requirement to take action through the courts if the government wanted to shut it down.
"Unfortunately we can't understand what the government is thinking because what they are doing on the ground is against the interests of Bahrain and the government itself."
