CBSE Circular No. - Acad. 09/2013 to CBSE

1. The School Based Assessment has been in operation in all CBSE affiliated schools for classes IX and X. As per the scheme, four Formative Assessments and two Summative Assessments are held in an academic year. The first Summative Assessment (SA–I) for this academic session for classes IX and X has been conducted in the second half of September 2012. 2. The following may please be noted for Summative Assessment II for class IX and Summative Assessment II (under scheme 1) for class X: a) The Syllabus and the design of the Examination Question Paper for different subjects of Classes IX and X Summative Assessment will be the same as communicated earlier through different circulars circulated by the Board. b) As in practice, the Summative Assessment–II will be in the form of a pen-paper test conducted by the schools themselves. c) In order to ensure standards, the Board will support schools to generate online question papers in the following major subjects w.e.f. this session.  English Communicative (Code No. 101)  English Language & Literature (Code No. 184)  Hindi Course A (Code No. 002)  Hindi Course B (Code No. 085)  Mathematics (Code No. 041)  Science (Code No. 086)  Social Science (Code No. 087)  Communicative Sanskrit (Code No. 122) - 2 – d) Evaluation of answer scripts will be done by the school teachers themselves on the basis of the Marking Scheme generated online as per the schedule given below. The schools may use the Sahodaya School Cluster for spot evaluation so that teachers from other schools are also involved. e) There will be random verification of the assessment procedures carried out by schools through the Board officials/nominees appointed by the Board. With respect to other subjects/languages, the schools will administer their own question paper. 3. The Board earlier used to provide Question papers and marking scheme to conduct the SA through CDs. This year the CBSE has decided to make the distribution system better and safer by providing each school with two sets of unique question papers generated through online software. 4. The school may: a. pick up one question paper for each subject b. mix and match the 2 question papers which are automatically generated from the system based on the Board‟s design. c. Prepare their own question papers as per design available on CBSE‟s website (cbseacademic.in). However, in case the school prepares its own question papers, the question papers and marking scheme so prepared should be emailed to the Board (email id: summative@cbseacademic.in) for verification within a week of conduct of the respective paper. 5. To distribute the question papers and marking scheme to schools, the Board has decided to use web-based technology and built a solution called “CBSE Integrated Test Management System (CBSE-ITMS)” The CBSE ITMS is an application that automates Question Paper and Marking Scheme generation and distribution. Question Papers and Marking Schemes are automatically generated online. This innovative solution allows the CBSE affiliated schools to access question papers and download them in a transparent, secure and user-friendly manner. The principals are requested to read Annexure I and register themselves in the system starting from February 1, 2013 to February 15, 2013. 6. Every School, Sahodaya Cluster or City may design its own date sheet for classes IX and X School Based Examination accordingly. 7. Schedule for Supply of Question Papers and Marking Scheme by the Board and Conduct of SA-II by the schools: Class Supply of Online Question Papers Conduct of Examination Supply of Online Marking Scheme IX From 5th March, 2013 10th March, 2013 to 20th March, 2013 From 19th March, 2013 X From 11th March, 2013 15th March, 2013 to 30th March, 2013 From 29th March, 2013 The principals are requested follow the steps in Annexure II to download the question papers and marking scheme. 8. The schools need to take the printouts of the desired question paper (refer para 4 above) and, thereafter, the required number of prints/copies may be made at the school level. These question papers must be kept carefully maintaining secrecy.
