The process for developing and monitoring the content of Palestinian school textbooks is set out in the First Palestinian Curriculum Plan 1998 and implemented by the Palestinian Curriculum Development Centre (PCDC). Under the process set out in the Curriculum Plan, the syllabus of each school grade and subject is evaluated both nationally and internationally. Draft textbooks are then presented to teachers' workshops for evaluation before being scrutinised by panels of academics. Following the initial print runs, further evaluation of each textbook is undertaken by the Assessment and Evaluation Centre. This includes feedback from teachers, content analysis by external experts and structured classroom observations.In addition to the monitoring process undertaken by the PCDC, a number of studies by respected research institutions have also reviewed textbooks used in Palestinian schools. Most recently, the US State Department has commissioned a full independent investigation into the content of Palestinian and Israeli school textbooks. This is due to report in 2012.
