The Indian National Chemistry Olympiad (INChO for short) is an Olympiad in Chemistry held in India.
The theory part of the INChO examination is held in end-January/beginning of February of every year. It is conducted by the Indian Association of Chemistry Teachers. School students (usually of standards 11 and 12) first need to qualify the National Standard Examination in Chemistry (NSEC) held in November of the preceding year. Among the 30,000+ students who sit for the NSEC, only the top 1% are selected for the INChO.
About 35 students are selected from the written examination. A total of 30 students are chosen from these to attend the Orientation-Cum-Selection-Camp (OCSC), chemistry, held at HBCSE, Mumbai.
Most students qualifying for the INChO are those completing their twelfth standard. However, in some cases, students have been selected for INChO at the end of the eleventh or tenth standard.
