Learning disabilities are disorders that affect brain functioning of understanding, reading, writing, spelling, reasoning or recalling ability. Learning disabilities can also cause problems in learning skills, language skills, mathematical operations and coordinating movements. Learning disabilities are continual and can cause continual life-long challenges. Children with learning abilities often have average or above-average intelligence.

 Diagnostic Test provides feedback on student's weaknesses and strengths in mathematics. This test may help teachers to find learning difficulties by identifying the ability, strengths, skills, and weaknesses of the students.

Steps of Diagnostic Testing:

• Identify students who are facing problems or need any academic assistance.
• Locating learning gaps and difficulties.
• Discovering causal factors of slow learning.
• Plan for specific efforts to overcome their problems and difficulties. Eg: Remedial Teaching. 

Diagnostic Assessment is used to identify areas of improvement for students and helps to guide them by knowing the gaps in their understanding. This test helps to recognize the issues that students have with the subject and helps to give proper instructions and feedback for better subject-related growth.

Learning Disabilities in mathematics can be assessed most appropriately by Diagnostic Test because it helps to know the difficulty in children's understanding.

 Aptitude test

• Aptitude tests are used for predicting success in future learning activities or occupations.
• Aptitude means the special ability or capacity besides the general intellectual ability which helps an individual to acquire a required degree of proficiency in a specific field.
• The aptitude tests are likely to test how an individual will perform in a specific area without proper guidance or training.
• These tests can be used to test the sensory and motor capabilities, aptitude in teaching, music, science, painting, mathematics, etc.
• These types of tests properly anticipate the future potentialities or capacities of an individual which helps us to select the best individual for a specialized activity.

​Achievement tests are administered on students to measure their learning outcomes. These tests are more prevalent in our schools. These tests show as to what has been learned by the students, rather than to predict future performance.
