Inspectors, testers, sorters, samplers, and weighers work with raw materials and fabricated parts, checking them for defects and making sure that these products conform to specifications. These jobs often become very involved, since workers need to use a variety of tools and charts to examine a wide range of products. Applicants for these positions need to have excellent attention to detail and communication skills since they will need to relay any defects or problems to their supervisor or to the manufacturer. Inspectors, testers, sorters, samplers, and weighers are all responsible for submitting formal reports and consulting manuals, making verbal skills essential. Also, a certain amount of dexterity is needed, as employees will have to handle materials carefully to avoid damaging them.

Assessments for Inspectors, Testers, Sorters, Samplers, and Weighers

Since attention and precision are such valuable skills in these positions, many employers choose to administer a test that evaluates a candidate’s attention and focus, such as the Criteria Attention Skills Test (CAST), to all applicants. The CAST quantifies an individual's ability to stay focused on a particular task without getting distracted by external stimuli. Another test that employers utilize to screen candidates for these roles is the Criteria Basic Skills Test (CBST). The CBST measures applicants' general skills that are highly correlated with job readiness, including verbal and math skills, attention to detail, and basic communication skills. The test has 40 questions and takes 20 minutes to complete. The score report includes a raw score, a percentile ranking, and provides valuable insight about an applicant's "trainability" and general preparedness to begin work.
