ASVAB Shop Information Practice Test: 135 Questions

Use this original ASVAB Shop Information practice test to build tools and shop-practices knowledge from zero. Official ASVAB sources call this subtest Shop Information, abbreviated SI, and describe it as knowledge of tools, shop terminology, and practices. This page turns that official public scope into a beginner study path, official timing context, 135 original questions, answer explanations, and internal links across the ASVAB content cluster.

Official Shop Information Scope

Shop Information, abbreviated SI, is an ASVAB Science/Technical-domain subtest. Official ASVAB materials describe it as knowledge of tools and shop terminology and practices. That description is intentionally broad. The official public ASVAB pages do not publish a full trade-school syllabus for SI, so this page separates official facts from original study material. The official facts define the subtest name, description, domain, timing, sample-question style, administration differences, and score relationship. The practice material below is original NUM8ERS content written to help a beginner learn the tool and shop language behind that official scope.

For a student with no shop background, SI is not only about naming tools. It is about knowing what a tool is for, what a process is called, what a safe procedure looks like, and which measurement or layout step belongs before cutting or fastening. The practical buckets are hand tools, measuring and layout, clamps and holding, cutting tools, drilling, fasteners, woodworking, metalworking, abrasives, finishing, machine safety, reading plans, and shop cleanup. These are learning buckets, not official ASVAB sub-scores.

Original practice notice: These 135 questions are original NUM8ERS study questions. They are not real ASVAB test questions, not leaked questions, and not copied from official sample items. Use them to build recognition, then follow official ASVAB instructions during the real test.

Timing and Test-Day Context

Official CAT-ASVAB information lists Shop Information as 10 scored questions with a 6-minute time limit when no tryout questions are present. The same official CAT-ASVAB timing table lists possible tryout questions and a longer time limit when tryouts appear. The official 2025 ASVAB fact sheet lists the paper-and-pencil Auto and Shop Information section as 25 questions in 11 minutes. Official fact-sheet language also explains that AI and SI are administered as separate tests in CAT-ASVAB but reported as one combined Auto and Shop score labeled AS; in P&P-ASVAB, AI and SI are combined into one AS test. This practice page is longer than the real SI subtest because it is built for learning and diagnosis.

Shop Information is not part of the AFQT calculation. Official ASVAB score guidance says AFQT uses Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge, and Paragraph Comprehension. SI can still matter for job matching because ASVAB subtests also feed Service composites. Use this page for shop practice, the ASVAB Study Guide for full exam logistics, and the score pages after you receive official scores.

How to Use This Practice Test

If you know nothing about shop work, begin with the job each tool performs. A saw removes material by cutting. A drill makes round holes. A file removes small amounts of metal or wood. A clamp holds work so your hands do not have to. A square checks or marks right angles. A level checks horizontal or vertical alignment. A vise holds work firmly. A fastener joins parts. A measurement tool prevents guesswork. Once those jobs are clear, the names become easier to remember.

  1. Read the beginner review before starting the first practice block.
  2. Answer questions 1-30 slowly and open every explanation.
  3. Label every missed question by topic: hand tools, measuring, layout, fasteners, cutting, drilling, woodworking, metalworking, abrasives, machines, safety, or plan reading.
  4. Retake missed questions after 24 hours without opening the answer first.
  5. When accuracy is above 80 percent, take 10-question timed sets in about 6 minutes.
  6. Use the ASVAB Automotive Information Practice Test for the paired Auto Information side of the combined AS score context.

Beginner Shop Review

Shop Information is vocabulary plus procedure. A beginner should learn tools in families: measuring tools, marking tools, holding tools, cutting tools, drilling tools, fastening tools, finishing tools, and safety equipment. On a test, the fastest way to remove wrong answers is to ask what job the question describes. If the question says "hold work while glue dries," think clamp. If it says "mark a straight line parallel to an edge," think marking gauge or square. If it says "tighten a bolt to a specified value," think torque wrench.

Measuring and Layout

Accurate shop work starts before cutting. A tape measure or rule measures length. A combination square can mark 90-degree and 45-degree lines and check squareness. A try square checks right angles. A framing square is useful for larger layout work. A level checks whether a surface is horizontal; a plumb bob or level can help check vertical alignment. Calipers measure inside, outside, or depth dimensions more precisely than a common rule. A micrometer is used for very precise thickness or diameter measurement. A scribe, pencil, awl, center punch, or chalk line helps mark work.

Layout terms matter. A cut line is where material will be cut. Kerf is the material removed by a saw blade. If the kerf is ignored, a board can end up too short. A centerline marks the middle. A pilot hole is a smaller hole drilled before a screw or larger drill. A countersink creates a tapered recess so a flat-head screw can sit flush. A clearance hole lets a screw shank pass through one piece while threads bite into another. Tolerance is the acceptable amount a measurement may vary from the target.

Hand Tools and Holding Tools

Common shop tools have specific jobs. A claw hammer drives and removes nails. A ball-peen hammer is often associated with metalwork. Screwdrivers match screw heads such as flat, Phillips, square, or hex. Wrenches turn nuts and bolts; open-end wrenches contact two flats, box-end wrenches surround the fastener, and socket wrenches use removable sockets. Pliers grip, bend, pull, or cut depending on the type. Needle-nose pliers reach tight spaces, locking pliers clamp onto work, and diagonal cutters cut wire or small pins.

Holding tools improve safety and accuracy. A bench vise holds work firmly on a bench. A C-clamp, bar clamp, spring clamp, or pipe clamp holds parts while cutting, drilling, gluing, or assembling. Clamping work keeps both hands available to control the tool. It also reduces movement that can make cuts crooked or cause drill bits to catch. A good shop habit is simple: secure the work before applying force.

Cutting, Drilling, and Abrasives

Cutting tools remove material. A rip saw cuts with the grain, while a crosscut saw cuts across the grain. A hacksaw cuts metal or plastic with a fine-tooth blade. A coping saw cuts curves in thin wood. A circular saw makes straight cuts with a spinning blade. A jigsaw cuts curves and irregular shapes. A drill makes round holes; drill bits must match the material and hole size. A drill press holds the drill vertically and gives better control than a handheld drill for many operations.

Abrasives shape and smooth surfaces. Sandpaper comes in grits; lower numbers are coarser, and higher numbers are finer. Coarse grit removes material quickly, while fine grit smooths before finishing. A sanding block helps keep the abrasive surface flat. A file removes small amounts of material and can smooth or shape metal. A grinder removes material rapidly but creates sparks and heat, so eye protection and correct guarding matter. Deburring removes sharp edges left after cutting or drilling.

Fasteners, Wood, and Metal

Fasteners join materials. Nails are driven by impact and are common in rough wood construction. Screws have threads and often hold better when removal may be needed later. Bolts are usually used with nuts or threaded holes. Washers spread load or protect surfaces. Lock washers or thread-locking methods help resist loosening. Rivets make permanent or semi-permanent joints. The wrong fastener can split wood, strip threads, loosen under vibration, or fail under load.

Wood and metal behave differently. Wood has grain, knots, and moisture movement. Cutting with the grain is different from cutting across the grain. Plywood is made from layers, while solid lumber is cut from a log. Metal may be ferrous, meaning iron-containing, or nonferrous, such as aluminum, copper, or brass. Steel is strong but can rust. Aluminum is light and corrosion-resistant. Soldering, brazing, and welding join metals in different ways; welding melts base metal, brazing uses filler metal at high heat without melting the base metal, and soldering usually uses lower temperature filler.

Shop Safety and Procedure

Shop safety is part of Shop Information, not an extra topic. Wear eye protection when cutting, grinding, drilling, or working near flying chips. Use hearing protection around loud machines. Keep guards in place. Disconnect power before changing blades or bits when appropriate. Tie back loose hair, avoid loose clothing near rotating machinery, and remove jewelry that could catch. Keep the work area clean because clutter causes slips, trips, and mistakes. Use the correct fire extinguisher for the hazard and store flammable materials properly.

Good procedure follows a sequence: read the plan, identify the material, measure carefully, mark clearly, secure the work, choose the correct tool, cut or drill safely, check the result, and clean the work area. Many SI questions reward that order. Do not cut before measuring. Do not drill without securing small parts. Do not force a dull tool. Do not remove a safety guard to save time. In shop work, accuracy and safety usually come from preparation rather than speed.

What Your Practice Result Means

This practice test does not produce an official ASVAB score. Official ASVAB scoring uses standard-score procedures, and SI is not part of AFQT. Use your result as a topic diagnostic. If most misses are from tool identification, study tool families first. If misses are from layout, review measurement, kerf, square, plumb, level, and tolerance. If misses are from machines or safety, slow down and connect each procedure to the hazard it controls.
