Calcutta: Calcutta High Court on Friday asked the authorities of Kendriya Vidyalaya's Ballygunge unit to inform by Tuesday whether it would be able include music and home science as subjects in its CBSE Class XII course.

Justice Tapabrata Chakraborty issued the order while hearing a petition filed by Debasish Das, the father of a Class XI student of the school who is dyslexic. Das has alleged that his son Samlap, 17, was not allowed to fill in the registration form for the CBSE class XII examinations.

Dyslexia involves a problem in reading despite normal intelligence. A person with dyslexia may have difficulty in spelling words, reading, writing, pronouncing when reading and understanding.

The CBSE curriculum offers special subjects for dyslexic students so that they can continue studies. Samlap had initially chosen special mathematics but found it too tough. He then chose music and home science with the school's consent but the school authorities allegedly refused to allow him to study the two subjects as it did not have the required affiliation to teach the subjects.

"In 2016, the school authorities had forwarded my client's application (to CBSE) to allow his son to study painting, music and home science instead of special mathematics. Now the school is refusing to accept the fact that the boy is dyslexic," Subrata Mukhopadhyay, Das's counsel, told the court during the hearing on Friday.

Samlap, who has been suffering from dyslexia since 2006, passed the Class X examination and was promoted to Class XI last year. His admit card identifies him as suffering from dyslexia.

Mukhopadhyay had told the court yesterday that the school authorities told Samlap's father in August that it did not have enough trained teachers to teach his son. The school allegedly asked Das to arrange for private tuitions.

But the authorities allegedly struck his name off the school register.

The school's counsel, A.K. Bag, told the judge that the school did not have the required CBSE affiliation to teach music and home science. He handed over some documents to substantiate his argument.

"The school did not have the affiliation to teach painting either. Then how is it providing painting lessons to students?" Justice Chakraborty asked.
