Happiness Scale : (English)

The outstanding aspect of this tool is to find out the probability of Learning Disability of the children with 80% sensitivity1 and 65% specificity2. The LDST recognizes children with Learning Disability scientifically and accurately. The tools that are available in the market now, do not have exclusive criterions for mentally and physically handicapped children. Whereas this test includes both, without any additional charges.

1 – Sensitivity = ability of a test to correctly identify those with the condition.
2 – Specificity =ability of the test to correctly identify those without the condition.
