CLOC provides training in all aspects of theatre technology. Highly experienced CLOC personnel supervise and assess students in the practical placement modules at tertiary educational institutions as well as work experience at secondary colleges.

In 1998 CLOC further recognised and encouraged the work of tertiary students by introducing an award for costume design at Swinburne University. The winner for 2001, Miranda Kalgovas, a final year Diploma in Theatre Technology-Costume student, created a series of striking contemporary designs for Chicago, for which she was nominated for Best Costume Design by the Music Theatre Guild of Victoria. She has since gone on to design costumes for several music theatre companies as well as CLOC, and has been the recipient of both nominations and awards for Costume Designer of the Year by the Guild. Similarly, Kelly Farrow, also a Swinburne Costume Design Award Winner, was nominated in 2005 for her Costume Designs for CLOC’s production of Steel Pier and worked with CLOC as Costume Co-ordinator for several years.

A production requires about two hundred people and there are opportunities for individuals to perform on stage or work behind the scenes. CLOC provides both theoretical and hands-on experience in every facet of theatre: set design, set construction and painting, costumes, props, hairdressing, orchestra, advertising, administration, stage management, choreography and directing. Indeed, CLOC productions are a fantastic way to gain experience while waiting for that "big break".

CLOC's achievements in education and training are evidenced by the successful careers of so many members in professional theatre. Suzanne Johnston, who started with CLOC as a chorus girl at the age of 16, and John Wegner, who started with CLOC as a young man, were CLOC performers before joining the Australian Opera as principals.

CLOC also provides the opportunity for many professional theatrical people to participate either on stage or in various aspects of productions on a totally voluntary basis, thus passing on their knowledge and skills to those starting out. Donald Cant who played the title role in the Sydney season of Phantom of the Opera and Gary Baade who was Jean Val Jean in the touring season of Les Miserables, are just two of the professionals who have returned to CLOC to perform in a non-professional capacity.

At the secondary level, CLOC provides a wide range of services to schools including: heavily discounted rates for the hire of costumes and props; technical assistance; guest lecturers; administrative and organisational know how.

CLOC is an integral part of the Victorian arts industry. Its strong commitment to presenting high quality musical theatre is evidenced by the profile of its performers and technicians. CLOC attracts over four hundred auditionees each year ranging in age from 15 to 72 with an average age of 28. Many of CLOC's performers and backstage workers are young. Each one is given every opportunity to fully participate in the many dimensions of contemporary musical theatre.
