1 AIM OF THE ADVISORY 1.1 The Curriculum Development Advisory (CDA) is a document to assist MOM Accredited Training Providers (ATP) with the instructional design and development of a competency-based training course for Workplace Safety and Health. It aims to help ATP facilitate the learning process, deliver effective training and conduct competency-based training and assessment. 1.2 This document contains key information on the Rigger and Signalman Course including the course aim, learning objectives, target audience, assumed skills and knowledge/entry requirements, course syllabus, recommended course duration, recommended class size, and recommended trainer/trainee ratio. It also sets forth guidelines for training delivery and assessment for the course.

1.3 This CDA will be reviewed on a regular basis and whenever it is deemed necessary due to changes in training syllabus or industrial requirements.

2 SCOPE OF THE COURSE 2.1 The Rigger and Signalman Course is aimed at providing individuals with the knowledge and skills to prepare and to tie the load for safe lifting by any form of lifting equipment using correct and clear signals to guide the crane operator in the manoeuvring of a load safely to its destination. This is a mandatory course in line with Workplace Safety and Health (Operation of Cranes) Regulations for individuals who are assigned to carry out the lifting operation of load involving a mobile crane or tower crane. While the CDA is written for an integrated Rigger and Signalman course, the individual roles of a rigger and signalman (stated in para 2.2) would need to be performed accordingly with due diligence. 2.2 Workplace Safety and Health (Operation of Cranes) Regulations 2011 stipulates that:

It shall be the duty of the responsible person:

to appoint a Rigger and/or Signalman before any lifting operation involving the use of any mobile crane or tower crane is carried out in the workplace;

not to appoint any person as a Rigger and/or Signalman unless the person is one who has successfully completed a training course acceptable to the Commissioner to equip him to be a Rigger and/or Signalman; and

to ensure that the Rigger and/or Signalman who is appointed is attired in such a way as would distinctively identify him as a Rigger and/or Signalman


It shall be the duty of the respective Rigger or Signalman:

not to rig up loads for any lifting operation by a mobile crane or tower crane unless he is a Rigger appointed by the responsible person

not to give signal to the crane operator unless he is a Signalman appointed by the responsible person

6 ASSESSMENT ADVISORY 6.1 General guidelines for conducting competency-based assessment.

6.1.1 The ATP is required to prepare an assessment plan (see Annex C for sample) for the Rigger and Signalman Course. The aim of the assessment plan is to determine the competency of the trainee to undertake the role of a Rigger and Signalman upon completion of the course.

6.1.2 The assessment plan must be directly related to all the learning objectives determined in the course. It comprises four main parts:

Overview of the assessment tools and its duration Instructions for the conduct of the assessment Instruments or tools of assessment (Question paper, checklist )


Assessment summary record

6.1.3 The assessment plan is subject to review on an annual basis by the ATP to ensure that trainees are constantly kept current and competent to perform up to the industrial requirements.

6.2 Principles of assessment

Assessment will be fair, valid, reliable and flexible for all trainees without deliberate barriers against the individual.

Fair – Are the assessments criteria clear? Do all the trainees know

what to expect from the assessment? Does the assessment disadvantage any trainee? Do the trainees have any recourse to appeal?

Valid – Are the assessment methods and tools appropriate and effective in assessing what they claim to assess. Are the evidence collected relevant to the training and demonstrates that the learning outcome has been achieved?

Reliability – Are the results consistent from one assessment to another? Do people have the confidence that the standards are applied consistently from learner to learner and from context to context?

Flexibility – Can the assessment be used for multiple assessments? Are the assessment tools and methods uniform across different approaches and drawing on a range of different methods? Can they be used appropriately to the context, task and individual under assessment?

6.3 Assessment tools and instruments

6.3.1 The ATP must conduct a Written Test (WT) and Practical Performance (PP).

Written test (WT) – This method of assessment is used to assess

the knowledge component of the Rigger course.

Practical Performance (PP) – This method is used to assess the skills to the actual task to be performed by the individual on the job.

6.3.2 The total allocated time for assessments (WT and PP) is 5.5 hours, comprising 1 hour for Written Test and 4.5 hours for Practical Performance, as follows:

6.3.3 Written Test (1 hour)


The written test shall comprise 40 MCQs with pass criteria of 60%.

6.3.4 Practical Performance (4.5 hours) The Practical Performance comprises assessment on rigging of at least two different types of loads from the standard loads in paragraph 5.3.3. Trainees will also be assessed on the use of 16 standard voice signals and 12 standard hand signals. There is the need for an assessment of trainee’s skills and knowledge of the hazard identification and risk assessment. The trainee’s competency should be assessed based on a checklist which determines whether he is “Competent” or “Not Yet Competent”. The recommended average duration per trainee is 15 minutes (minimum) for the practical performance. 6.3.5 Trainees must pass both the WT and PP to be considered to have successfully completed the Rigger and Signalman Course. No re-sit for any assessment is allowed unless the trainee has attended the course again.

6.4 Briefing to trainee

6.4.1 The briefing to trainee is to explain the purpose and context of assessment so as to ensure that there are no surprises during the conduct of assessment.

6.4.2 The briefing to trainee should include

the assessment requirements and process, including clear instructions on each of the assessment to be taken

trainee’s rights & process of appeal to assessment outcome

6.4.3 During the briefing, assessors must take the opportunity to

confirm with trainee on any special needs & explain how needs will be addressed during assessment.

6.4.4 Assessor must seek feedback and clarify trainee’s understanding of assessment requirements before commencement of the assessment.

6.5. Conduct of assessment 6.5.1 Assessment must be conducted strictly in accordance with the

assessment plan. In particular, each trainee must complete all the assessment requirements in the time allocated. All safety procedures must be complied.

6.5.2 An assessment on the competency of the trainee must only be

made based on the evidence gathered. The evidence for each of the


assessment instrument is given in the suggested response to the WT and the checklist accompanying the PP.

6.6 Recording and reporting of assessment outcome 6.6.1 All assessment outcomes must be accurately recorded in the

assessment summary record form. 6.6.2 Assessment outcome will be communicated to the trainee. 6.6.3 The ATP shall maintain a record of the assessment results for 2

years for audit by MOM. 7 TRAINER AND ASSESSOR REQUIREMENTS 7.1 A trainer and assessor of this Rigger course should possess all of the following:

WSQ Advanced Certificate in Workplace Safety and Health (WSH Professional Level B) or equivalent

Lifting Supervisor Safety Course certification At least 5 years experience as a supervisor/foreman/safety

personnel in lifting operations Advanced Certificate in Training and Assessment (ACTA) or

equivalent 8 END OF COURSE EVALUATION AND FEEDBACK 8.1 The ATP shall conduct an end-of-course evaluation at the end of each course. Trainees shall be allowed to provide quantitative and qualitative feedback on the course content, duration, training delivery, training materials, training venue, training resources, quality of trainers and assessors. 8.2 The ATP shall monitor the end-of-course evaluation and feedback closely to ensure that the ratings are consistently 3 and above. Immediate action should be taken whenever the ratings fall below 3. These actions should be properly recorded and kept for audit inspection.
