When it came to mathematics in India, the top 10 national schools were ranked in the top three places in terms of enrolment.
As per the 2016 National Math Index, India had 4.6 lakh students and a GDP of USD 8,943 crore.
The ranking is based on the enrolment rate, the ratio of enrolments to the number of students, and the average student growth rate.
The index measures the average growth rate of students in the national education system.
The top 10 ranking schools are:Arunachal Pradesh (2.6%), Bihar (2%), Haryana (1.9%), Madhya Pradesh (1%), Punjab (1%) and West Bengal (1%).
The rankings were released by the Ministry of Education.
According to the 2017-18 National School Profile, the number and percentage of students enrolled at national and state level in all subjects, including maths and natural log, improved significantly from 2015-16.
In the year 2015-2016, the average enrolment at national level was 2.8 lakh and in the state level, the enrolments were 6.3 lakh.
The average growth in enrolment was 4.1% for the year 2016-17.
In the 2017 rankings, the states had a slight drop in enrolments, as compared to the previous year.
For the first time, the state-level enrolments in math, natural log and geometry were higher than the national level.
For physics, the growth was only around 3.5%.
In all other subjects, growth was less than 5%.
The national average growth was 6.2% for this year.
The growth in the number, the percentage and the growth in growth rate were also higher than 2015-19.
The number of enrollees per teacher, number of teachers per class, and growth in number of teacher per class were the key factors for the ranking of schools in the 2016-2017 National School Profiles.
The National Math Profiles also showed that there was a huge growth in enrollments in the second year of the curriculum, which is why the top schools had higher enrolment and growth.
However, the National Math index is not a measurement of performance of schools.
It measures the performance of the system.
It has a few indicators like the enroling rate, average growth, growth rate and the number or percentage of teachers.
In these, the performance has to be judged in the context of the overall performance of a school.
