CBSE 12th

Dear Gaurav,
The two sources of entry to Indian Revenue Service are the officers directly recruited through Civil Services Examination conducted by UPSC and officers promoted from Income Tax Officers (Class-II) grade.
To enter into a career as IRS officer / officer grade directly one has to pass the Civil Service Examination conducted by UPSC. The minimum qualification required for applying for CSE is graduation from a recognised university. Candidates, who have attained 21 years of age but not attained 30 years of age on August 1st of the year of examination are eligible to apply.
Civil Service Examination is in two stages- preliminary and main. The preliminary examination (prelims) is the process through which candidates are short listed for the main written examination. Candidates qualifying the main (written) exam are called for personal interview. Based on the marks secured in the main (written) and interview, a merit list is drawn up, which determines the choice of service. The exam is usually held in the month of April.
Junior Grade - For junior level entry into the revenue service, one has to pass the Combined Graduate level Examination by the Staff Selection Commission. This is a less rigorous selection procedure as compared to the Civil Services Examination. Graduates of any discipline between 18 and 27 years are eligible to apply for this exam.
