1st Stage Computer Based Test (CBT): Common for all notified posts of this CEN 01/2019.



The 1st Stage CBT is of screening nature and the standard of questions for the CBT will be generally in conformity with the educational standards prescribed for the posts. The normalized score of 1st Stage CBT shall be used for short listing ofcandidates for 2nd Stage CBT as per their merit. Candidates who are shortlisted for 2nd Stage CBT availing the reservation benefits of OBC (NCL)/ SC/ ST/ EWS, PwBD and ExSM shall continue to be considered only against OBC (NCL)/ SC/ ST/ EWS, PwBD and ExSM for all subsequent stages of recruitment process.

2nd Stage Computer Based Test (CBT):
Separate 2nd Stage CBT shall be taken for each of the 7th CPC Level i.e. Level 2, 3, 4, 5 and 6 with graded difficulty level. All posts falling within same level of 7th CPC shall have a common 2nd stage CBT. If candidates are eligible for more than one level of 7th CPC posts as per their educational qualifications, they have to give common 1st stage CBT and corresponding 2nd stage CBT for each level of 7th CPC as per the table given below in "Summary of all Stages".
Shortlisting of Candidates for the 2nd Stage CBT shall be based on the normalized marks obtained by them in 1st Stage CBT and the options for various posts exercised by them keeping in view the educational qualification of the candidate i.e. 10+2 or Graduate. Total no. of candidates to be shortlisted shall be 20 times the community wise vacancies of posts notified against the RRB as per their merit in 1st Stage CBT cum choice of posts. However, Railways reserve the right to increase/ decrease this limit in total or for any specific category(s) as required to ensure availability of adequate candidates for all the notified posts.
The examination duration and number of questions for 2nd stage CBT are indicated below:



Minimum percentage of marks for eligibility in various categories: UR-40%, EWS40%, OBC (Non creamy layer)-30%, SC-30%, ST-25%. These percentages of marks for eligibility may be relaxed by 2% for PwBD candidates in case of shortage of PwBD candidates against vacancies reserved for them.
The normalized marks scored by the candidate in the 2nd stage CBT shall be used for short listing the candidates for document verification for the posts which do not have Typing Skill Test/ Computer based Aptitude Test. For the posts having Typing Skill Test/ Computer based Aptitude Test, the normalized marks scored by the candidate in the 2nd stage CBT shall be used for shortlisting the candidates for Typing Skill Test/ Computer based Aptitude Test.

Computer Based Aptitude Test (CBAT) (Only for candidates who have opted for Traffic Assistant and Station Master)
Qualifying marks: The candidates need to secure a minimum T-Score of 42 marks in each of the test batteries to qualify. This is applicable to all candidates irrespective of community or category i.e. irrespective of SC/ ST/ OBC-NCL/ EWS/ PwBD/ Ex SM and no relaxation in the minimum T- Score is permissible.
Candidates equal to 8 times the number of vacancies of Station Master (SM)/ Traffic Assistant (TA) for each of the communities i.e. UR, OBC-NCL, SC, ST and EWS (including ExSM) shall be short listed for CBAT based on their performance in 2nd Stage CBT from among the candidates who have opted for the post of SM/TA. Such shortlisted candidates should produce the Vision Certificate in the prescribed format as per Annexure VI [Click Here] in original during CBAT, failing which they will not be permitted to appear in the CBAT.
The SM/ TA merit list will be drawn only from amongst the candidates qualifying in the CBAT, with 70% weightage for the marks obtained in the 2nd Stage CBT and 30% weightage for the marks obtained in CBAT.

Based on the performance of candidates in 2nd Stage CBT and based on the performance of candidates in both 2nd Stage CBT and CBAT/ TST (as applicable), candidates equal to the number of vacancies will be called for Document Verification as per their merit and options. In addition, candidates equal to 50% (may increase or decrease at the discretion of RRBs) of the number of vacancy for various posts will also be called for document verification.

These additional candidates will, however, be considered for empanelment only if there is a shortfall in empanelment from the merit list or/and as replacement against the shortfall on account of not joining of recommended candidates in the working post or/and any other special requirements.

In case of two or more candidates securing same marks, their merit position shall be determined by age criteria i.e., older person shall be placed at higher merit and in case age being same, then alphabetical order (A to Z) of the name shall be taken into account to break the tie. Appointment of selected candidates is subject to their passing requisite Medical Fitness Test to be conducted by the Railway Administration, final verification of educational and community certificates and verification of antecedents/ character of the candidates.

Candidates may please note that RRBs only recommend names of the empanelled candidates and appointment is offered ONLY by the respective Railway Administrations.

Medical Standards for the Posts
Candidates called for document verification will have to pass requisite medical fitness test(s) conducted by the Railway Administration to ensure that the candidates are medically fit to carry out the duties connected with the post(s) opted by them. Visual Acuity Standard is one of the important criteria of medical fitness of railway staff. The medical standards are outlined below:


Different Medical standards shall apply to Ex-Servicemen as detailed in Para 534 of Indian Railway Medical Manual (IRMM) Volume I, which may be accessed at www.indianrailways.gov.in.
Candidates are advised to ensure that they are eligible as per the medical standards for the post(s) opted by them. In case of failure of the candidate to pass the prescribed medical fitness for the opted posts, he will not be considered suitable for empanelment for that post and no alternate appointment will be provided.

The summary of the various stages of recruitment process detailed as above for the notified posts are tabulated below:

Normalisation of Marks:
Short listing of Candidates for various stages shall be based on the normalized marks obtained by them whenever CBT is conducted in multiple sessions for the same syllabus. The normalization scheme to be adopted for 1st Stage CBT and 2nd Stage CBT is detailed in following paragraphs.
Calculation of Normalized Marks for Multi-Session Papers:
In 1st Stage CBT, for some 7th CPC Levels in 2nd Stage CBT and for CBAT, the examination may have to be conducted in multiple sessions. For these multisession papers, a suitable normalization is applied to take into account any variation in the difficulty levels of the question papers across different sessions.
The formula for calculating the normalized marks for the multi-session papers is detailed below:
Normalization mark of [latex]j^{th}[/latex] candidate in [latex]i^{th}[/latex] session [latex]\widehat{M}_{ij}[/latex] is given by:
[latex]\widehat{M}_{ij}[/latex] = [latex]\frac{\overline{M}_{t}^g - {M}_{q}^g}{\overline{M}_{ti} - {M}_{iq}}({M}_{ij} - {M}_{iq}) + {M}_{q}^g[/latex]
[latex]{M}_{ij}[/latex]: is the actual marks obtained by the jth candidate in [latex]j^{th}[/latex] session.
[latex]\overline{M}_{t}^g[/latex]: is the average marks of the top 0.1% of the candidates considering all sessions.

[latex]{M}_{q}^g[/latex]: is the sum of mean and standard deviation marks of the candidates in the paper considering all sessions.
[latex]\overline{M}_{ti}[/latex]: is the average marks of the top 0.1% of the candidates in the ith session or marks of topper if session strength is less than 1000.
[latex]{M}_{iq}[/latex]: is the sum of the mean marks and standard deviation of the [latex]i^{th}[/latex] session
