Ayesha has answered this, but I found out some interesting things about Binet from previous module I was taking which looked at the various methods to measure intelligence. Binet was actually interested not in filtering out the cleverest students, but in helping those who were falling behind. I'm not sure Binet would enjoy seeing the development of intelligence tests overtime to give more opportunites to those already excelling.
Another interesting fact about Binet was that he prior to working on intelligence testing worked alongside the enduring French neurologist Jean-Martin Charcot.
I'd like to quote from my university book:
"...it was his view that disadvantaged children could be prepared for school , and their intelligence could be developed with mental exercises. In the right environment , with the right support, intelligence could grow". (Banyard, P et al, 2014)
Banyard, P. Byford, J. McAvoy, J. (2014) 'Measuring Intelligence' in Investigating Intelligence
French psychologist Alfred Binet created the first intelligence test for students assessment.
