Abstract: Two annual migrations of nomadic tribes have a large impact on school work and learning of students. This study is a qualitative case study and intends to examine the impact of a reduction in teaching time in nomadic schools. In order to assess the students’ absence from school each year due to two migrations and its negative effects, the researcher used mixed method research(Quantitative-Qualitative) to thoroughly study the phenomenon and to collect data during the two academic years (2011/2010 and 2012/2011). The study sample consists of students of a nomadic school where the researcher has worked as a teacher. The results indicate that the annual migration of nomadic tribes is the cause of decrease in training time by 34% (55 days from 160 days) and subsequently leads to disruption of school planning, hastily teaching of the contents, and not completion of textbook by the end of the school year.
