History of CBSE

What is the meaning of CBSE:The Central Board of Secondary Education is an eminent board of school education in India. The CBSE prepares the syllabus for Class 9 to Class 12 in schools affiliated with it. It conducts two major examinations every year, the All India Secondary School Examination (AISSE) for Class 10 and the All India Senior School Certificate Examination (AISSCE) for Class 12, which is a school-leaving examination. Many private schools within and outside India are affiliated to CBSE. The medium for education prescribed by CBSE is either English or Hindi. The CBSE also conducts the All India Engineering Entrance Examination (AIEEE) which is a common entrance examination conducted on all-India basis for admission to engineering and architecture/planning programmes in the country. Similarly Pre-medical and Pre-dental Tests AIPMT (PMT/PDT) are conducted for medical and dental colleges. Syllabus and methodology of CBSE makes it much convenient for students to opt for pure sciences, medicines, engineerings and IIT. Most successful students of competitive examinations,IITJEE, KVPY, science olympiads, mathematics olympiads are nurtured at CBSE.
HISTORY OF CBSE:The "United Provinces Board of High School and Intermediate Education" was the first Board set up in 1921 with jurisdictions over Rajputana, Central India and Gwalior. The Government of India in 1929 suggested to set up a joint Board to expand the jurisdiction and renamed it the "Board of High School and Intermediate Education, Rajputana", which included Ajmer-Merwara. In 1952, as a result of the growth of State Universities and State Boards all over India, the constitution of Board was amended wherein its jurisdiction was extended to part-C and part-D territories and the Board was given its present name "Central Board of Secondary Education", it was in the year 1962 finally that the Board was reconstituted. There are a total of 10,011 schools in India, and outside India, affiliated to CBSE. As a result of the reconstruction, the Delhi Board of Secondary Education was merged with the Central Board and all the educational institutions recognised by the Delhi Board also became a part of the Central Board. The Board has grown from a group of 309 schools in 1962 to 10,011 schools as on date, which include 981 Kendriya Vidyalayas, 1381 Government Schools, 2486 Independent Schools, 355 Jawahar Navodaya Vidyalayas and 13 Adhoc Schools. There are also Indian schools in the Middle East and Southeast Asia that are affiliated to it.In most of countries Government of India employee's Children and Indian Embassy's children go to CBSE schools abroad generally called Indian Schools. In Japan Indian education under CBSE school has gained popularity. CBSE examinations for classes X and XII are conducted in the month of March and the first week of April. The results are declared in the last week of May mostly in 2-3 phases. These results can be seen on the official site. CBSE123.blogspot.com is mainly intended for 10 and 12 CBSE students. However, this can be used for Entrance exams like AIEEE. The CBSE questions are selected in such a way that if they are able to attend these questions, they will be confident of understanding the concepts. This site is purely an educational portal and here i am keeping CBSE sample papers and CBSE questions bank.CBSE Stands for Central Board of Secondary Education.
