The concept of having one standard for every subject is something the Federal Government has tried to do for elementary and high school education. This will then push the question on children's pre-school preparations by families. This then leads to issues of socio-economics and parenting differences.
Basically - we will have students with diverse incoming abilities. And yet, many believe we should have standard outcomes.
What this means - we have differing input - but expect similar output.
This means - the "Processing of Students" - must be different if the output is to be standardized.
This begs the question - what is the expected "Standardized Output?"
And since we use a gradient system to evaluate student performance. - Should the Standard Output mean students with an "A" meet the standard?
Thus, the alternative is then:
If student input is different, and student output is different - then students with an "A" in one system would be meeting a minimum level of standardization. Does this mean an "A" from a University equate to a "C" standard at another institution?
In today's social norms environment - students expect to receive an "A" in something the put forth an effort (Participation, which is driven by social norms of equality). If this is the case - then what does an "A" represent?
If the "A" represents a minimum standard or a "D" level at other schools - then is this inappropriate?
The real questions is - what are the expectations of employers who hire different students? Does an employer who hires a graduate from a University (with an "A" grade) perceive the student to be at a higher level than a student from another school who received a "C" grade?
What is the "Scope & Scale" of the learned KSA - Knowledge Skills and Abilities that each student receives within the different schools?
Here inlies the problem - Many schools want to be perceived as equal so they may attract students within a competitive environment. They will promote they are a "University for Education" and yet they use LOW entrance requirements - this means they are accepting many students with much lower levels of preparation for learning.
The total input is lower. Thus to reach standardized output - the processing (Pedagogy) must be different than other schools in order to achieve similar output standards.
This is no different than the dichotomy of Standardized Industrialization vs Entrepreneurship or Republicanism vs Communism or even Democracy.
Even in Leadership studies there is a divide between those who believe there are specific standard competencies that make a leader - rather than the individual.
