The Barbados National Council of Parent-Teacher Associations (BNCPTA) is investigating allegations that some Frederick Smith Secondary School students were locked out of the school on Tuesday morning.In an interview with Barbados TODAY on Wednesday, concerned general secretary Nicole Brathwaite said she was actively seeking answers.A video making the rounds on social media on Tuesday showed several school children standing outside the gate of the Trents, St James school.In an accompanying voice note, an upset parent claimed the principal had locked the children out at 9:15 a.m. and had used inappropriate language in speaking to the students.When contacted, principal Stephen Jackman declined comment and Barbados TODAY’s efforts to reach Chief Education Officer Dr Ramona Bradshaw-Archer were unsuccessful.Brathwaite said if the security and principal conducted themselves in an inappropriate manner, they should be dealt with accordingly. However, she said, if it was a case of disciplinary action, that was a different matter.
