Testing for Intelligence?

Why are they testing for intelligence? I was born and raised in Detroit, MI testing was not just for intelligence but to see if a child should be placed in pre school or wait for kindergarten, they even made it where a child didn't have to go to the kindergarten first they could start at the first grade but would not test the child to see if they were able to learn at the same pace as the first graders. Therefore a lot of public school children  were being left behind a grade because of that.

The recent South African Report on the National Assessments (ANA), showed that the poorest schools fared worst in national assessment tests.
The ANA written in February 2011, involving almost six million learners in primary schools throughout South Africa represents one of the most significant proactive interventions by Government to strengthen the foundational skills of Literacy and Numeracy among South African learners.
The report showed that primary school children from the provinces Mpumalanga, Limpopo, and Northwest could not even reach the basic skill levels for literacy and numeracy. The reason for this according to the Minister of Basic Education, Angie Motshekga is socio-economical.
Nationally learners in Grade 3 obtained an average of 35 % for literacy and 28% for literacy and 30 % for numeracy.

Children should be assessed when it is educationally necessary, when they are transfering from another school and have been living in a different state, or if they have been in foster care, when they have skipped the kindergarten because their parent didn't make them go and really didn't teach them anything while they were at home, assessments should be done when a child is more advanced then the other children and is able to learn at the same pace as an older child. Children should be assessed for medical and mental reasons. It should be done when it is deemed to be necessary.
