This master thesis deals with aims in teaching and testing writing in ELT. It primarily examines the current shape of treating writing as a language skill at elementary schools in the Czech Republic where there has been recently implemented a new curricular policy. The thesis turns attention to the requirement of aligning aims of teaching and testing writing with one another as well as with those formulated in curricular documents, which encourages beneficial backwash and achieving aims stated by the sector. For this purpose, Blooms' revised taxonomy for learning, teaching and assessing is introduced and consequently used in the practical part of the thesis which investigates the level of correspondence among aims stated in the projected curriculum and those of teaching-learning and testing tasks in the seventh grade of elementary school.
