Maintenance roles often involve interpreting complex information, reading technical diagrams, and applying problem-solving under time constraints. Aptitude assessments measure critical cognitive abilities like spatial reasoning, mechanical understanding, and attention to detail—helping employers identify those capable of diagnosing and resolving issues accurately and efficiently.

In technical support roles, these assessments can also predict success in roles that require fast learning, process improvement, or multitasking under pressure.

Core Competencies Assessed:

• Mechanical Reasoning

• Spatial Awareness

• Attention to Detail

• Problem-Solving

• Information Processing

• Learning Agility

Maintenance and technical support roles—such as mechanics, electricians, and workshop supervisors—require a high level of reliability, task focus, and accountability. Behavioural assessments help mining companies identify candidates who demonstrate a strong work ethic, attention to procedure, and the ability to work safely and independently, often in high-pressure or time-sensitive situations.

These assessments also help identify individuals who are a good fit for team-based environments, or who have potential for leadership within workshops or site-based support teams.

Core Competencies Assessed:

• Reliability & Accountability

• Task Orientation

• Compliance with Procedures

• Stress Tolerance

• Independence & Initiative

• Team Collaboration

• Leadership Potential (for supervisor roles)

With regular exposure to high-risk equipment, hazardous materials, and complex machinery, safety is central to all maintenance and technical support positions in mining. Safety assessments—like Testgrid’s SSA—evaluate key traits such as risk aversion, rule-following behaviour, and situational awareness.

These assessments allow mining companies to identify individuals who are more likely to take safety seriously, follow procedures, and respond appropriately in emergencies—reducing incident risk and supporting compliance with WHS obligations.

Core Competencies Assessed:

• Risk Perception

• Rule Adherence

• Safety Compliance

• Hazard Recognition

• Situational Awareness

• Conscientiousness
