Open Book Test

The New Mexico GS-30 Plastering, Stucco and Lathing Contractor exam is commonly prepared for as an open book, reference-based exam. Open-book testing allows candidates to use approved references during the exam, but it still requires preparation, organization, pacing, and familiarity with the books, codes, and standards. Candidates who have not practiced with the references may lose valuable time searching for code provisions, OSHA safety topics, ASTM requirements, lathing details, stucco application rules, gypsum construction topics, or accessory specifications.

An open-book exam rewards candidates who can identify the subject quickly and use the correct reference efficiently. The goal is not to read large sections during the exam. The goal is to recognize whether a question involves New Mexico code, IBC, IRC, OSHA, an ASTM standard, gypsum construction, or Portland cement plaster, then locate the correct information and apply it to the facts provided.

A practical open-book workflow includes:

• Identify the trade topic: Decide whether the question involves lathing, stucco, gypsum, plaster, steel framing, trim accessories, exterior walls, safety, or building code requirements.
• Choose the correct reference: Use the building codes for code provisions, OSHA for safety, ASTM standards for technical material and installation requirements, the Gypsum Construction Handbook for gypsum topics, and the Portland Cement Plaster Manual for stucco preparation.
• Use the reference structure: Practice locating tables of contents, indexes, definitions, sections, tables, figures, standard headings, material requirements, installation procedures, and application guidance.
• Read carefully: Plastering and lathing questions may depend on the substrate, material, application type, framing condition, accessory, attachment, plaster system, safety hazard, or code context.
• Apply the reference: Connect the standard, code, manual, or safety rule to the specific field condition described instead of choosing an answer from memory alone.
• Review mistakes: Determine whether missed questions came from wrong reference selection, poor navigation, misunderstood terminology, missed details, or incorrect application.

Students should use this book package to develop a repeatable lookup routine before exam day. Open-book preparation becomes stronger when candidates repeatedly practice moving from question wording to the correct reference, chapter, ASTM section, table, figure, definition, diagram, or code provision. The more familiar the references become, the easier it is to answer questions with better pacing and less stress.
