The Caribbean Union of Teachers has warned that it is prepared to escalate the action taken by Barbadian teachers who say they will not submit final School Based Assessment (SBA) marks for students.

The union says this could include taking protest region-wide.

The Barbados government has already warned teachers that they could face disciplinary action if they maintain their position.

The government has accused the Barbados Secondary Teachers' Union and the Barbados Union of Teachers of being unreasonable.

The teachers are demanding adequate compensation for conducting the SBA programme being administered by the Caribbean Examinations Council (CXC).
