There is Lateral Entry Scheme to admit diploma holders to the second year/third semester of the BTech courses to acquire a degree in engineering based on a state-level entrance examination.

There was a proposal to convert CET to a Centre of Excellence, upgrading it to 'Kerala Institute of Technology (KIT)', so that a technical university can grow around it,[5] but the plan was later dropped to form a new separate single university for all engineering colleges in the state, named KTU.

The department of Chemistry of College of Engineering Trivandrum is also an approved research centre under University of Kerala.

Opportunities exist for candidates to do full-time as well as part-time research in the college with registration under APJ Abdul Kalam Technological University.

College of Engineering, Trivandrum is also an approved Minor Centre under AICTE QIP (Quality Improvement Programme) providing opportunities to faculty members of the degree-level engineering institutions to improve their qualification by offering admissions to Master's and Ph.D. degree Programme.

[19] SAE INDIA CET regularly holds educative sessions on automotive technology- from bicycles and skateboards to trains and rockets.

In 2000, it hosted the Student Professional Awareness Conference (SPAC 2000) in Technopark with many notable speakers from the Information Technology domain.

One affinity group called IEEE Women in Engineering is running under this Student Branch and six societies.

Ever since its formation, ISTE Students Chapter has helped its members scale heights of technical excellence through the numerous events it has conducted.

The ISTE Student Chapter has successfully organised intra-collegiate tech fests such as Prarambh, Exodus, Semfiesta and Persona along with several talks, workshops, quizzes and business events every year.

The club aims to inspire and educate minds, inculcating erudition and enabling a deeper understanding of the subject through theoretical discussions and technical contributions.

CET QC conducts weekly informal sessions and other regular quizzing events in college.

One of the most awaited annual quizzing event, Eroteme, is conducted by the QC and attended by quizzers in and out of the state.

The idea behind a community like TinkerHub is for students, to get exposed to technology, resources and people, outside of the curriculum and to enhance interaction between multiple departments, with year of study, being no bar for entry.

What one faces when stepping out of college is a world of competition and without a strong backing of the latest in technology, making a name for oneself will be hard.
