IntroductionThis Study Guide has been developed by the Newfoundland and Labrador Department ofAdvanced Education, Skills and Labour, Apprenticeship and Trades Certification Division, toassist apprentices and trade qualifiers as they prepare to write the Interprovincial (IP) Red SealExam. IP Exams are available for all Red Seal trades. For a list of Interprovincial trades pleaserefer to the Department of Advanced Education, Skills and Labour Some of the specific goals of this guide are: to help you understand the skills and knowledge that might be covered on the exam to help you identify your strengths and weaknesses to provide organization and structure for a course of study to provide a list of resources to help you with your study plan to support and supplement the teaching and learning processThis study guide outlines the theoretical portion of the program. The intent is not to replacetechnical training provided under the guidance of instructors. Rather, it is a tool to be used inconjunction with formal training.Study Guide Machinist 20193

Exam ContentUnderstanding the National Occupational Analysis (NOA)The NOA is a document used for Red Seal trades that describes the knowledge, skills andabilities required by a fully competent tradesperson working in that trade. The content for theIP Red Seal exam is based on the NOA. The NOA is an excellent tool to use as you study for theRed Seal exam. NOAs can be found at www.red-seal.ca.NOA material is organized into major content areas called BLOCKS. The blocks are furtherbroken down into TASKS and SUB-TASKS.NOAStudy Guide Machinist 2019BlocksBlocks Tasks Sub-tasks9

NOA Pie ChartThe NOA Pie Chart presents the block percentages in the form of a pie chart which tells you theapproximate number of questions from each block. For example, 9% of the questions on theMachinist Exam will be based on Block A.MACHINISTH13%G8%A9%B9%F6%C8%D23%E24%Block TitlesBlock ACommon Occupational SkillsBlock EConventional Milling MachinesBlock BBench WorkBlock FPower SawsBlock CDrill PressesBlock GPrecision Grinding MachinesBlock HComputer Numerical Control (CNC)Machine-ToolsBlock D Conventional Lathes10Study Guide Machinist 2019

Exam BreakdownThe Machinist IP Red Seal Exam has 135 questions. The following table shows a breakdown ofthe approximate number of questions that come from each NOA block.

NOA Sub-tasksThe following NOA Task Profile Checklist outlines the blocks, tasks and sub-tasks for your trade.The IP Red Seal exam is written to test your knowledge and abilities regarding the sub-tasks inthe NOA. This chart can be used to review your current knowledge. You can review by placinga checkmark ( ) next to those you understand fully.Place your focus on those you do not understand and study them until you are comfortablewith the material. Think of possible questions in that particular content area.The NOA also contains a list of “supporting knowledge and abilities” for each sub-task. Theyare the skills and knowledge you must have to perform a sub-task. The supporting knowledgeand abilities identified under each sub-task will be very helpful as you review. The list can befound in the NOA for your trade.12Study Guide Machinist 2019
