The inception of Tinsukia College in the year 1956 was the result of the strenuous efforts of late B.K. Saraswatji who mobilized all required resources with the help of like minded citizens of Tinsukia district to give rise to this great institution. Without their support and patronage, the college would never have come into being. Before the collee came to be located in the present premises at Kachujan in 1961; it started out in the premises of Senairam High School on 1st September 1956.  The college was started as an Arts college initially at Intermediate level but in the very next year Commerce Stream was also introduced. In 1957 itself the college was upgraded to Degree level. The year 1964 has a special significance in the annals of Tinsukia College when Science Stream was also added making it a full - fledged multi faculty Degree College. For an institution to rise to this level within 8 years of its inception is a feat in itself. By 1964, the college conducted courses under the auspices of Gauhati University but after establishment of Dibrugarh University in 1965, it was brought into the jurisdiction of the said University. Till 1961, the college had been running on public contribution and generous donations from philanthropists; but in 1962 the college was accorded the status of "Deficit Grant-in-Aid" college which enabled it to receive financial grants from the Govt. of Assam. Later on, the college was recognised by the UGC, New Delhi which resulted into receipt of plan financial assistance from UGC for various development schemes. Two years back, the Govt. of Assam took a historic dicision to provincialise all deficit grant-in-aid college & as a result w.e.f 1st December 2005 the college enjoys the status of "Provincialised College".

The college grew from strength to strength on the merit of its students, the dedication of its teachers & the vision of the principals. An institution which began its academic endeavor with handful students and four faculties; has currently a student enrollment of more than 2300 & permanent faculty strength of 78. The Co-ed institution has been imparting education both at Higher Secondary & Degree levels in three Faculties of Arts, Science & Commerce. It has altogether 17 teaching departments offering a wide range of choices to the students.

The College has an infrastructure built on a sprawling campus covering area of 18 bighas. The facilities includes a big library, well stocked with Books & Journals, Photocopier, Computers, Well equipped Laboratories, Girls hostel, Career Information and Guidance Cell, Media Centre, a Canteen, Canopy etc. As per the recommendations of NAAC an IQAC has also been established to improve the quality of education and support services offered by the college to its stake holders.

In response to the evolving needs of the students and economy for market oriented professional courses, the college has initiated necessary steps to start professional academic programmes. As a result in 2005 the college managed to establish the "Centre for Management Education" to launch 3 years BBA course under Dibrugarh University. The department of Zoology has also started a certificate course in Bio-informatics in association with DOEACC, Guwahati (Ministry of Communication and IT, Govt. of India).

Since the demand for quality education is growing leaps & bounds, their is an urgent necessity to upgrade the present infrastructure of the college. Sensing the winds of change, the Governing Body of the college has initiated the construction of the state-of-the-art library building at a projected cost of around Rs. 80 lacs in the year 2006. So far, ground floor of the library building is almost complete covering approx. area of 6000 sq. ft. The college authorities take this opportunity to appeal the enlightened citizen to come forward & extend their helping hands to accomplish this mission.
