Damankonyili (Northern Region), 12 Oct. The Ghana Education Service has been urged to demarcate school lands in the rural communities to avoid encroachment. Alhaji Baba Ihrahimah, Tamale Municipal Chief Executive, said most schools in the Tamale township, cannot expand due to encroachment on school lands.

Alhaji Ibrahimah said ''the assembly is committed to improving education in the municipality and has embarked on a crash programme to ease the over population in the basic schools''. '' The efforts of the assembly will be defeated if the schools are not rpt not put into proper use'', he said and appealed to parents to enrol their children especially girls in the schools. He appealed to the GES to set up an effective monitoring and supervision team to check the performance of teachers in the rural area. Alhaji Ibrahimah also commissioned a block for the Choggu Junior Secondary School built at a cost of 84 million cedis. The Choggu Naa Salifu Alhassan, thanked the municipal assembly for the assistance and pledged to ensure that all school going age children go to school.
