“Educational needs”
Different students learn in different ways and are also at different levels of cognitive development. Schools need to try to meet the needs of all students the best they can. Some students are visual learners others are process (doing) learners. Students enter school and each grade with a different set of skills and knowledge. A teacher has to take these students and teach them in ways so all achieve and obtain knowledge and skills. There is no curriculum that meets the needs of all students.
“There is no curriculum that meets the needs of all students.”
I suppose by “curriculum” you means teaching methods. And there are no teachers who can jump through all the hoops simultaneously and be a personal tutor to each student.
In a competitive world, the curriculum is mandatory as far as what is offered. Those of us who are not math geniuses study something else, for example. But the study of basic simple math is not optional.
I have a problem with the meme “meeting the needs of student.” There should be more emphasis on “measuring up.” Athletics, for example, are not designed to meet needs; success depends on hard work and developing the necessary skills.
Ditto school curriculum.
