The JDMIS is committed to providing the best possible education and experience to its students! It gives me great pleasure to make the following declaration with regard to the school's core policies...

Student to Teacher Ratio and Teaching Staff

There are no more than 36 students to 1 teacher in any of the JDMIS’ theory classes. During practical training portions of JDMIS Courses this ratio is improved to only 12 students to 1 teacher in order to ensure each student receives ample attention and assistance as they learn skills critical to their success in the jewellery industry. The JDMIS has three full-time teachers on staff and five part-time professional jewellery instructors.

Classrooms and Facilities

The JDMIS has seven specialized classrooms with a total seating capacity for up to 108 students and an open-plan dynamic student practice space and resource area with additional capacity for 10-25 students. These facilities include all the tools and equipment needed to provide an exceptional learning experience, including computers, projection and visualization systems, jewellery-equipment such as induction casting equipment, a hydraulic press, burnout furnace and vacuum mixer, plating and polishing equipment, 3D wax printer, high-temperature kiln, magnetic finishing tools, flex-shaft rotary finishers, rolling mills and much, much more...

Instructors and Governing Boards

The JDMIS maintains an academic board whose purpose is to review the school's procedures and policies with regard to the quality and direction of its training. Board members include Myself, Mr. Bhavik Bhatt and Mr. Alex Zupancich. The schools examinations board, whose responsibility includes administration of policies and procedures related to assessments and examinations comprise myself, Alex Zupancich and Bhavik Bhatt.

Students at the JDMIS are ensured rewarding training experiences by the quality of their instructors. All JDMIS instructors and visiting instructors are experienced artists, educators and/or industry members and are selected because of their knowledge and passion for the jewellery field. While many may not have stratospheric qualifications themselves, such documents matter little in the a vocation such as jewellery - where artistic ability, industry experience and strong ability and desire to share knowledge are paramount.

Organizational Structure

The JDMIS is a small and specialized school; run by experienced and capable entrepreneurs who understand the key to the school's success is the operation of an efficient, student focussed and quality driven enterprise. While formally, the school maintains a series of distinct roles within the organization, in practice the school managers and team members fulfil many of these roles simultaneously, and more efficiently than with large numbers of departments and staff. Students are likely to interact with JDMIS registration and student services staff on a regular basis, but otherwise operational and management issues will be raised to either myself or the Managing Director, Alex Zupancich. The school also maintains inventory, maintenance, accounts, design and marketing related staff on full or part-time bases. The school's board of directors (ie: overall managers of the school) may be found here.

Transparent Pricing and Refund Policies

The JDMIS maintains policies and procedures aimed at ensuring its staff and agents represent the courses we offer clearly and accurately. All marketing documentation clearly states pricing information and JDMIS course prices are inclusive of required tools and materials, mean students will never find themselves having to pay more to complete the supervised project work that is part of the JDMIS curriculum and take with them the tools they need to continue practicing the skills they have learned (please note however that students are free to supplement these materials for self-study projects completed outside of Diploma contact training hours). The JDMIS is a GST registered company and all fees paid to the JDMIS are subject to the prevailing Singapore Goods and Service Tax. Qualifying tourists may request a GST refund for the tools and materials provided as part of the course.

The JDMIS is aware that circumstances may arise that make it impossible for a student to complete their course of study. When these circumstances affect the JDMIS ability to offer a scheduled course, the school will always offer a refund to its affected students. Where students withdraw from our programmes for personal reasons, the JDMIS is willing to offer full or partial refunds according to clearly stated notice requirements.

Established Feedback Channels and Grievance Redress Policies

The JDMIS recognizes that there are always opportunities for improvement and maintains an open feedback channel by means of its student services staff. In instances of misunderstandings or disputes between students, with faculty or against the school itself the JDMIS follows a clear grievance resolution process that includes external mediation and arbitration as a last resort.

Standard Student Contract for Diploma Courses

All prospective local and international students participating in JDMIS full-time diploma programs are required to enter into the Standard Student Contract before course admission. Sample of this Standard Student Contract can be viewed at Council for Private Education's website or you may request a copy of this contract from the School. A copy of the relevant contract is included in the admissions documentation sent to all students accepted into JDMIS Diploma programmes.

The JDMIS is committed to providing superior education as well as a safe and fair educational environment for its students and we are proud to participate in the education trust mark program- In the past the school was accredited under CASETrust for Education and is currently pursuing the Singapore Edutrust certification.

Fee Protection Scheme

With the introduction of the Private Education Bill, all students' fees will be insured under the Fee Protection Scheme (FPS). The FPS serves to protect the international and local student's diploma tuition fees in the event that a Private Education Institution (PEI) is unable to continue operations due to insolvency and/or regulatory closure. Furthermore, the FPS protects the student if the PEI fails to pay penalties or to return fees to students arising from judgements made against it by the Singapore Courts.

The JDMIS adopts the FPS Insurance for international and local students having entered into a Standard PEI Student Contract with the JDMIS for its full-time diploma programs. The FPS Insurance offers insured students protection against the following events:

  • Loss of course fees paid in advance by the insured student to the JDMIS and not refunded, if the student cannot start or complete his/her course as a result of the JDMIS becoming insolvent or being required by the Singapore authorities to stop operations.
  • The JDMIS fails to pay the sum awarded by Singapore Courts to the insured student, where such an award relates to a dispute between the JDMIS and the insured student on course fees paid by the insured student to the JDMIS.
  • S$10,000 benefit payable covering the insured student's accidental death or total permanent disability by accident.

The JDMIS has appointed Liberty Insurance Pte Ltd to be the FPS providers for its students. The insurance coverage will be for the entire course fee and any course fees arising from an extension of the study period longer than the initially planned study period (if applicable).
