Is it up to the teacher or the school to provide the school year curriculum?

Basic curriculum is provided by government to keep standard education quality in whole of country. The school develops and modifies the curriculum based on that standard and modify it to school's objectives. Teacher design lesson plans based on the school curriculum and as Mrs. Zafar said, the teacher implements it. 

FOR SURE IT MUST BE SCHOOL MANAGEMENT DUTY TO DESIGN & PROVIDE THE CURRICULUM TO TEACHERS ,,,,,,,,,,, THEY HAVE TO IMPLEMENT THAT IN THE WORKING DAYS.

In most countries, you have to take a standardised test after you finish highschool, so the teacher should follow the national curriculum. In countries where this is not the case, the school should define the curriculum from first grade until the last, so there is a continuity and students do not have knowledge gaps.

I agree with the answer added by: Ismi Puji Hastuti  

IT IS A SHARED JOB WHICH SHOULD BE PERFORMED BY BOTH SIDES

As an educator, I think designing curriculum should not be left to the individual teacher. Primarily, the curriculum should fulfill the needs and aspirations of the nation as a whole.

Take, for example, a country in the middle east with a large oil wealth. This country can have a curriculum which can produce Petroleum Engineers, Chemical Engineers, Entrepreneurs, etc., which can get employment with ease in the respective fields.

If you take the example of countries like Germany or Japan, they should have students who can become competent persons in automobile industry, electronic industry, entrepreneurship, etc., which can help them to get employment locally.

In short, designing curriculum should be a national responsibility.

For international schools, curriculum such as IB, IGCSE, etc., are suitable that prepare students to meet global challenges.

the teacher is the most knowlegable person in the teachinh arena so i see that it is apt to the teacher to prepare the curriculum and thus students will learn only what is teachable and what is not.

I think it is up to the teacher and the pupils.

School Management is responsible to provide the curriculum to teacher. As teacher is not decision make in that area or else  has provide all the relevant information to design.  

I would agree that a curriculum is an integrated document that is in line with a school's educational philosophy, student profile and resources to maximise curriculum delivery that is relevant, accessible and enjoyable for students.

Experienced teachers often develop their own stock of curriculum material which they adapt, differentiate and extend for each school. This is invaluable when teachers work as substitute/cover teachers.

Perhaps in advertising for teachers with their own developed curricula, the school is looking for someone who can shape and influence a department and make improvements?
