It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for Teachers. Cambridge International will not enter into discussions about these mark schemes. Cambridge International is publishing the mark schemes for the October/November 2023 series for most Cambridge IGCSE, Cambridge International A and AS Level components, and some Cambridge O Level components.

0445/13 Cambridge IGCSE – Mark Scheme PUBLISHED October/November 2023 © UCLES 2023 Page 2 of 10 Generic Marking Principles These general marking principles must be applied by all examiners when marking candidate answers. They should be applied alongside the specific content of the mark scheme or generic level descriptors for a question. Each question paper and mark scheme will also comply with these marking principles. GENERIC MARKING PRINCIPLE 1: Marks must be awarded in line with: • the specific content of the mark scheme or the generic level descriptors for the question • the specific skills defined in the mark scheme or in the generic level descriptors for the question • the standard of response required by a candidate as exemplified by the standardisation scripts. GENERIC MARKING PRINCIPLE 2: Marks awarded are always whole marks (not half marks, or other fractions). GENERIC MARKING PRINCIPLE 3: Marks must be awarded positively: • marks are awarded for correct/valid answers, as defined in the mark scheme. However, credit is given for valid answers which go beyond the scope of the syllabus and mark scheme, referring to your Team Leader as appropriate • marks are awarded when candidates clearly demonstrate what they know and can do • marks are not deducted for errors • marks are not deducted for omissions • answers should only be judged on the quality of spelling, punctuation and grammar when these features are specifically assessed by the question as indicated by the mark scheme. The meaning, however, should be unambiguous. GENERIC MARKING PRINCIPLE 4: Rules must be applied consistently, e.g. in situations where candidates have not followed instructions or in the application of generic level descriptors. GENERIC MARKING PRINCIPLE 5: Marks should be awarded using the full range of marks defined in the mark scheme for the question (however; the use of the full mark range may be limited according to the quality of the candidate responses seen). GENERIC MARKING PRINCIPLE 6: Marks awarded are based solely on the requirements as defined in the mark scheme. Marks should not be awarded with grade thresholds or grade descriptors in mind.

Part (c) Communication of ideas Suitable designs Mark Performance description Mark Performance description 5-6 Ideas are communicated with precision and clarity through the use of accurate drawings and reasoned annotations linked to most of the requirements. 5-6 Creative solutions which fully meet the requirements. Designs showing most aspects of construction detail. 3-4 Ideas are displayed with some clarity through clear drawings supported by annotations referring to some of the requirements. 3-4 Sensible solutions that mostly meet the requirements. Designs with moderate construction detail. 1-2 Simple drawings and limited annotations show little understanding of the requirements. 1-2 Solutions do not meet many of the requirements. Simplistic designs with little construction detail. 0 No creditable response. 0 No creditable response Part (e) Quality of drawing Construction details Mark Performance description Mark Performance Description 4 High standard of line quality, use of colour and proportions. Appropriate techniques used that show clearly all detail. 5-6 All construction detail clear with good annotations and/or additional detail drawings as necessary. 2-3 Good line quality, use of colour and proportions. Most of the detail presented. 3-4 Most construction may be obvious from overall views or with some annotation. 1 Poor line quality and proportions. Little detail presented. 1-2 A simplistic design; little or no detail of construction used. 0 No creditable response. 0 No creditable response.

0445/13 Cambridge IGCSE – Mark Scheme PUBLISHED October/November 2023 © UCLES 2023 Page 4 of 10 Guidance on using the performance description tables Marking should be positive, rewarding achievement where possible but clearly differentiating across the whole range of marks available. In approaching the assessment process, examiners should look at the work and then make a ‘best fit’ judgement as to which level statement it fits. In practice the work does not always match one level statement precisely so a judgement may need to be made between two or more level statements. Once a ‘best fit’ level statement has been identified the following guide should be used to decide on a specific mark: • Where the candidate’s work convincingly meets the level statement, the highest mark should be awarded • Where the candidate’s work adequately meets the level statement, the most appropriate mark in the middle of the range should be awarded • Where the candidate’s work just meets the level statement, the lowest mark should be awarded.
