Technical DrawingTechnical Drawing is a visual means of communicating clearly and concisely all the information(drawings, dimensions, notes, specifications) necessary to transfer an idea or concept into reality.It is based on the principles of projection in two-dimensional and three-dimensionalrepresentations. Technical Drawing plays an indispensable role in determining the quality andcompetitiveness of finished products in the design process. It is, therefore, an importantprerequisite and an essential companion for the CSEC Industrial Technology programmes whichprovide the foundational competencies in manufacturing and industrialisation in the Caribbean.The syllabus focuses on the development of competencies in geometric construction, descriptivegeometry, engineering designs and graphics, electrical, mechanical, manufacturing andconstruction drafting. These are geared toward the development of students’ spatial visualisation,technical communication, interdisciplinary and employability skills. These skills are useful forcareers in drafting, architecture, surveying, civil engineering, interior designing, designengineering and in the general construction and manufacturing industries.

Technical Drawing Syllabus RATIONALETechnical Drawing is a visual means of communicating clearly and concisely all the information(drawings, dimensions, notes, specifications) necessary to transfer an idea or concept into reality. Itis based on the principles of projection in two-dimensional and three-dimensional representations.Technical Drawing has its most common application in the field of manufacturing, engineering,architecture and construction where it is used to document and support the design process. This isaccomplished by communicating ideas about the shape, form, dimensions, materials, manufacturingmethods and finishes of articles to be produced. Technical Drawing plays an indispensable role indetermining the quality and competitiveness of finished products in the design process. It is,therefore, an important prerequisite and an essential companion for the CSEC IndustrialTechnology programmes which provide the foundational competencies in manufacturing andindustrialisation in the Caribbean.The syllabus focuses on the development of competencies in geometric construction, descriptivegeometry, engineering designs and graphics, electrical, mechanical, manufacturing and constructiondrafting. These are geared toward the development of students’ spatial visualisation, technicalcommunication, interdisciplinary and employability skills. These skills are useful for careers ineducation, drafting, architecture, surveying, engineering (robotics, fabrication and civil), interior,spacial and structural, engineering designing, and in the general construction and manufacturingindustries. In addition, the programme of studies in the syllabus caters for those students who willseek entry level employment in related fields.The formulation of the syllabus takes into consideration the development of selected attributes of theIdeal Caribbean Person as documented in the 2000 Caribbean Education Strategy. This person is onewho is emotionally secure with a high level of self-confidence and self-esteem; is aware of theimportance of living in harmony with the environment; demonstrates multiple literacies,independence and critical thinking; values and displays the creative imagination in its variousmanifestations and nurtures its development in the economic and entrepreneurial spheres in all otherareas of life.The Technical Drawing syllabus integrates the principles of Competency Based Education, Trainingand Assessment (CBETA) in the School-Based Assessment component. This strategy is consistent withthe seamless articulation among CXC’s qualifications to facilitate an appropriate balance betweenthe academic and technical subjects and to improve work-based performance. These competenciesalign with the UNESCO Pillars of Learning – learning to know, learning to do, learning to livetogether, learning to be and learning to transform one’s self and society.CXC 13/G/SYLL 151

AIMSThe syllabus aims to:1.enable students to acquire an understanding of the relationship of design and drawing inmanufacturing and industrialisation;2.provide students with the competencies required for understanding, interpreting andproducing technical drawings aligned with established standards, conventions andtechnology;3.develop students’ critical thinking, quality standards and teamwork skills in the productionof drawings using traditional methods or design software packages;4.develop students’ appreciation of creativity, imagination and aesthetics in designs anddrawings;5.provide students with foundation competencies in entrepreneurial skills for employmentcreation and economic development. ORGANISATION OF THE SYLLABUSThe syllabus is divided into four (4) Sections:SECTION 1-Fundamentals of Technical Drawing(a)(b)SECTION 2-Occupational Health, Safety and the Environment.Equipment, Tools, Materials, Lettering, Line Work, Dimensions andScales.Geometrical Construction(a)(b)Plane Geometry.Solid Geometry.SECTION 3-Building DrawingSECTION 4-Mechanical Engineering DrawingCandidates are expected to undertake SECTION 1: Fundamentals of Technical Drawing, SECTION 2:Geometrical Construction and EITHER SECTION 3: Building Drawing OR SECTION 4: MechanicalEngineering Drawing. RECOMMENDED TEACHING APPROACHIn developing the plan to deliver and assess the syllabus, the teacher is asked to carefully note theareas of the syllabus that overlap with the Units of Competence in the Regional OccupationalCXC 13/G/SYLL 152

Standards. These Units of Competence are tied to the SBA component and should be delivered andassessed concurrently.The teacher is encouraged to combine institutional and industry training (dual) to facilitate studentslearning. Students are to be exposed to a wide range of activities that will allow them to haveauthentic learning experiences. This may be facilitated through projects, field studies, industryattachment, partnerships with National Training Agencies and the use of simulators and/or othervirtual activities. SUGGESTED TIMETABLE ALLOCATIONIt is recommended that a minimum of six 40-minute periods per week, over two academic years orthe equivalent be allocated to the syllabus. Single periods are not recommended.ALLIED SUBJECTSCandidates should be encouraged to include the following subjects in their programme of study:One of the Industrial Technology subjects (Building Technology; Mechanical Engineering Technology;Electrical and Electronic Technology), English A, Mathematics, Physics. CERTIFICATIONThe Technical Drawing course is an integral component of the Technical and Vocational Educationand Training (TVET) programme offered by the Council. It will be examined for certification atTechnical Proficiency. A candidate’s performance will be indicated on the certificate by an overallnumerical grade on a six-point scale as well as a letter grade for each of three profile dimensions,namely, Knowledge, Application and Practical Ability. Candidates have the option of using eitherthe Traditional Drawing Method (drawing board and tee square) or Computer-Aided Drafting (CAD)method/applications.The School-Based Assessment component for this syllabus is aligned to selected Units of Competencewithin the regional qualification of the Caribbean Vocational Qualification (CVQ). Through thisintegration every student with acceptable grades, where applicable may exit with recognition ofcompetencies for the drawing unit from the Level 1 Caribbean Vocational Qualification (CVQ) in:1.General Construction (CCBCG10102), Draw and interpret simple drawings (BCGCOR0031A);2.Furniture Making (CCLMF10103), Read and interpret work documents (LMFCOR0071A);3.Electrical Installation (CCMEM11002), Draw and interpret sketches and simple drawings(MEMCOR0091A); or,4.Metal Work Engineering (CCMEM10302), Draw and interpret sketches and simple drawings(MEMCOR0091A).The decisions to award competencies will be based on the quality and relevance of the evidencespresented to the occupational area.CXC 13/G/SYLL 153
