The chemistry program for 9(th) grade put into action in 2007. However the applicability of this renewed program necessitates pre-service and in-service training of teachers. For that purpose, it is planned that an effective IST (In service training) program should be developed and applied on teachers to effectively implement The New Chemistry Program for 9(th) grade at secondary education. Driven by this idea, this study has been prepared to detect IST needs of chemistry teachers. To that end, with 37 chemistry teachers located in Trabzon city center, a 1-day seminar has been organized to detect the needs. During this seminar, questions related to IST needs have been directed to teachers in a group discussion section. At the end of analyzing obtained data, IST priorities of chemistry teachers have been identified. (C) 2010 Elsevier Ltd. All rights reserved.
