The document discusses reasons for excluding school subjects from the curriculum. Some reasons include: a subject being outdated or irrelevant to student needs; containing useless material; not matching student interests or skills; and students not learning effectively. Other reasons are: lack of available resources or learning materials; insufficient infrastructure; inability to complete activities in the timeframe; difficulty in assessment; and lack of expert teachers. The document argues that subjects should be excluded if they do not meet learning outcomes or have available qualified teachers.
