In life, as in education, the most valuable and meaningful factors are not quantifiable.
A major problem with education today is the fact that the competence of teachers and the quality of schools are measured by these quantifiable factors, many of which are not important in the learning of the students.
The factor underpinning quality teaching and learning is 'relationships' which of course cannot be quantified.
