Crucial for chemical industry practitioners! New standards are coming for the grading assessment of chemical unit operators.

It is understood that the 123 occupational standards released this time cover multiple sector fields, including various practical occupations such as chemical unit operations, pigment production workers, organic silicone production workers, and daily chemical product formulators/testers (hydrogen fuel cell testers). The focus is on skilled positions in key areas like manufacturing production, new materials, and new energy, aligning with current labor demands to manufacturing research.

Among them, the occupational standard to Chemical Unit Operator has garnered significant sector attention.

According to the general notice, Chemical Unit Operators mainly refer to practitioners who operate various chemical unit equipment such as filtration, heat exchange, evaporation, distillation, and extraction to complete material processing. This occupation covers multiple specialized sub-categories, specifically including Chemical Filtration Worker, Chemical Distillation Worker, Chemical Extraction Worker, Chemical Evaporation Worker, Chemical Absorption Worker, Chemical adsorptive processes Worker, Chemical Drying Worker, Chemical Crystallization Worker, Chemical Centrifugal Separation Worker, Chemical Granulation Worker, Chemical Washing Worker, and Phenol Removal Worker, comprehensively covering all positions in the basic chemical production operation process.

Regarding the setting of vocational skill levels, the publicly released standards implement a graded and classified system to different chemical sub-categories, with a greater precise and detailed hierarchy.

Overall, the general occupation of Chemical Unit Operator has five skill levels, ranging from low to high: Level 5/Primary Worker, Level 4/Intermediate Worker, Level 3/cutting-edge Worker, Level 2/Technician, and Level 1/Senior Technician.

to specialized sub-categories, the level settings are differentiated.

Among them, the skill systems to three positions—Chemical Washing Worker, Chemical Filtration Worker, and Chemical Centrifugal Separation Worker—are relatively basic, with only three levels set: Level 5/Primary Worker, Level 4/Intermediate Worker, and Level 3/cutting-edge Worker. The four occupations of Chemical Evaporation Worker, Chemical Drying Worker, Chemical Crystallization Worker, and Chemical Granulation Worker involve higher skill standards and broader technical dimensions, so four levels are established, adding the Level 2/Technician level on top of the primary, intermediate, and cutting-edge workers.

The publicly released standards also clarify unified and standardized vocational skill assessment methods, divided into three major categories: theoretical knowledge examination, operation skill assessment, and complete review, adapted to the assessment needs of skilled talents at different levels.

Among them, the theoretical knowledge examination mainly takes the form of closed-book written tests or computer-based tests, focusing on assessing essential basic professional norms, professional theory, and related knowledge to practitioners. The operation skill assessment adopts various methods such as on-site operation, simulated operation, simulation operation, oral test, and closed-book written test, either singly or in combination, to core-ly test the actual job operation skills and practical levels of practitioners.

The complete review is specifically tailored to the evaluation of high-end skilled talents, targeting only the two high-level grades of Level 2/Technician and Level 1/Senior Technician. Through reviewing consumption materials and professional defense, it conducts an all-around complete assessment and review of the practitioner's professional literacy, technical ability, and work experience.

Regarding scoring, all assessment subjects consumption a 100-point scale. A candidate is considered qualified if they achieve a score of 60 (inclusive) or above in the theoretical knowledge examination, operation skill assessment, and complete review.

sector insiders stated that the revision and general discharge of these 123 occupational standards further refine the competency standards, level systems, and evaluation rules to skilled positions in key industries. This not only provides clear guidance to practitioners to enhance their vocational skills and grade recognition however also provides an authoritative basis to corporate employment evaluation, skilled talent cultivation, and standardized sector research, helping to promote the professionalization and standardization of the skilled talent workforce. All sectors of society are encouraged to actively provide feedback and suggestions during the general notice period to help further optimize and enhance the occupational standards.
