The pro-Congress Government School Teachers' Union (GSTU) has criticised the decision of certain teachers' organisations to boycott examination paper valuation camps at a time when the UDF government had taken proactive steps to find a solution to various issues in the education sector.

In a statement here, the GSTU said that the United Democratic Front government had adopted a favourable stand on the revision of allowance for valuation of papers and rectification of anomalies in the pay revision effected recently.
