Competency framework

Skill expectations by proficiency level.

emerging
Rock and fluid samples — collect and label following established protocols at supervised field or laboratory sites.Laboratory apparatus and testing equipment — operate under direct supervision to perform standard analyses on geological samples.Test results and operational data — compile and log into standardized forms or databases with guidance from senior technicians.Geological sketches and field notes — prepare using established templates under the direction of a project geologist.Technical reports and sampling logs — draft preliminary sections by compiling data from field observations and laboratory output.Spreadsheet software and office suite tools — enter and organize geochemical or geophysical data for review by supervising staff.Testing and mechanical equipment — perform routine inspections and minor adjustments following written maintenance procedures.Professional and scientific literature — read assigned reports to extract relevant geological and geophysical data under guidance.Geographic information system software — input spatial data and generate basic map layers with direction from experienced staff.Field survey activities including prospecting trips and well-logging programs — participate as a team member under close professional oversight.
developing
Solid and fluid samples — collect, prepare, and preserve using appropriate methods selected for specific lithological or geochemical conditions.Laboratory testing equipment and analytical instruments — operate routinely to determine mineral content, chemical characteristics, and physical properties of samples.Operational and testing data logs — compile, verify, and maintain with reduced oversight, ensuring accuracy for downstream analysis.Geological maps and cross-sections — draft using CAD and map creation software based on field measurements and borehole data.Sampling and analysis reports — prepare clear technical documents summarizing findings and preliminary interpretations for project review.Geophysical and geochemical survey programs — support field execution by coordinating logistics and recording observations across multiple survey sites.Testing and electrical equipment — troubleshoot and repair common malfunctions in the field or laboratory to minimize operational downtime.GIS and mobile location-based services software — use to navigate field sites, capture spatial data, and produce working map products.Geological and geophysical prospecting reports — read and synthesize published findings to inform sampling strategies and data interpretation.Time and task scheduling — manage personal workload across concurrent field and laboratory assignments with limited supervisory input.
proficient
Complex sample suites from exploratory drilling and mine survey programs — analyze and interpret autonomously, applying inductive reasoning to identify lithological trends.Multi-parameter laboratory analyses — design and execute testing protocols that address non-routine geological questions across varied sample types and environments.Large geochemical and geophysical datasets — compile, query, and analyze using database and analytical software to support resource evaluation decisions.Detailed geological maps, stratigraphic cross-sections, and geologic models — produce independently using GIS, CAD, and graphics software for professional deliverables.Comprehensive technical and professional reports — author, review, and finalize documents presenting sampling findings, data analysis, and actionable recommendations.Exploratory drilling and well-logging operations — lead technical participation, evaluating subsurface conditions and recommending adjustments to drilling programs in real time.Testing, electrical, and mechanical equipment — diagnose and resolve complex failures, and develop preventive maintenance schedules to sustain laboratory and field operations.Regional geological and geophysical literature — critically evaluate and integrate findings to refine prospecting models and support resource estimation workflows.Interdisciplinary field survey programs — coordinate field-data collection across geological, geochemical, and geophysical methods to meet project objectives on schedule.Quality control procedures for sample handling and data recording — implement and audit throughout the project lifecycle to ensure data integrity and regulatory compliance.
advanced
Organizational sampling and testing standards — develop and institutionalize best-practice protocols that govern laboratory and field operations across multiple simultaneous projects.Geological technician teams — mentor, evaluate, and develop personnel at all experience levels to build sustained departmental technical capability.Integrated geological, geophysical, and geochemical survey programs — lead program design, resource allocation, and execution strategy at the organizational or regional scale.Strategic exploration decisions — inform senior leadership by synthesizing complex multi-source datasets into clear, evidence-based geological interpretations and risk assessments.Professional technical reports and regulatory submissions — review and approve final deliverables, ensuring scientific rigor, compliance, and stakeholder clarity.GIS, analytical software, and database infrastructure — oversee selection, implementation, and governance to maximize data quality and cross-project interoperability.Equipment procurement and maintenance programs — direct capital planning and vendor management to ensure that field and laboratory technology meets evolving operational demands.Cross-functional project teams including geologists, engineers, and environmental scientists — coordinate contributions and resolve technical conflicts to achieve integrated project outcomes.Industry literature, emerging methodologies, and regulatory developments — monitor continuously and translate insights into updated organizational practices and competitive exploration strategies.Organizational quality assurance and safety culture — champion rigorous attention to detail, integrity, and cautiousness as governing principles across all geological technician operations.
