The IWSP provides students with unique learning opportunities to achieve the following objectives:

1. Applied learning –  integration of theory and practice, acquisition of specialist knowledge and development of professional skills.
2. Exposure to real-world conditions- appreciation of real-world constraints in respective industry contexts to develop skills of adaptability, creativity and innovation, while adding value to the workplace.
3. Smooth transition to jobs-practical experience which shortens work induction period, translating to higher productivity and lower training costs to future employers of SIT’s graduates. The work experience acquired may also contribute to professional accreditation/certification requirements if applicable.

The IWSP is an integral part of applied learning as it provides an opportunity for students to integrate what they have learnt in the classroom to what is practised in the real world, and vice-versa. The extended period of IWSP with students performing real work also provides an opportunity for companies to evaluate the suitability of students as potential employees. In effect, the IWSP is equivalent to the probation period. The student will also have ample opportunity to immerse in the industry’s business and culture and decide if this is a good industry to work in. Besides producing practice-oriented graduates, IWSP will also be the platform through which students will be challenged during their work attachment stint to initiate innovative projects under the guidance of SIT’s IWSP Supervisors and Company appointed Work Supervisors. Through such projects, students will have the opportunity to develop innovative solutions for the projects they have identified. In this way, the IWSP will be a key platform that contributes to the inculcation of the SIT-DNA in every student.
