Foundation Mathematics – MA103 2025 VCE Assessment Guide VCAA Marking Policies and Procedures Consistency of Marking The Assessment Guide indicates the basis for awarding marks for each item. This may involve either counting correct answers/features of a response or marking holistically, whereby making a judgement about the overall quality/qualities of a response. The Assessment Guide will demonstrate how marks are to be awarded for a response, not where or how marks are to be deducted. The Assessment Guide will address specific examples and relevant application where appropriate. The following provides a checklist that all assessors should follow for consistent approaches to marking VCE external examinations. Assessors should contact the Chief Assessor in cases where they believe that by following any of the directions below, a student will not be marked fairly. Assessors must use the final version of the Assessment Guide as confirmed at the end of the Assessor Training Meeting. Concern Advice Responses ‘off task’ or contradictory A response that does not address the subject of the question cannot be awarded any marks. If contradictory responses are given (i.e.: the response conflicts with earlier comments or working out) full marks cannot be awarded. Responses not addressed in the Assessment Guide Assessors should refer the matter to the Chief Assessor for determination. Spelling Unless otherwise instructed in the Assessment Guide (i.e.: as part of a criteria), incorrect spelling should not affect the scoring of a student’s response. © VCAA Foundation Mathematics MA103 – Assessment Guide 2025 Specified Number of Examples/Reasons Where a student provides more than the required number, the assessor should only assess the required number of responses. These should be assessed in the order in which they appear. Working Out Where a question explicitly requires the student to show working out, and this is specified in the examination instructions or in the question, full marks should be awarded if: The response is correct and the working out is correct Two sets of working out are shown, both attempts are correct, and the answer is correct Where a question explicitly requires the student to show working out, partial marks should be awarded for correct completion of key steps required to produce the correct answer. Consequential Errors Where a question requires a series of sequential steps to arrive at the correct response, the Assessment Guide will allocate marks for the key steps required to produce the correct response. In these cases, the effect of a consequential error on a subsequent response will be considered. Half Marks Half marks must not be awarded for a response or carried over to subsequent questions. Crossing Out If a student response has been crossed out, the part crossed out should not be considered. If the entire response is crossed out, this is awarded zero (‘0’). Modules Where a student responds to more modules than required, the assessor must assess all responses. Options Where a student responds to more than one option, the assessor must assess all responses according to the criteria in the Assessment Guide and award the student the highest score, indicating the option selected. Not Attempted vs Zero (0) Where a student has not made a genuine attempt to respond to the question, assessors should score the response as ‘Not Attempted’. This may include: Blank responses ‘I don’t know’ Repeating the question, task, source material, or any other text directly from the examination A response with no relevance to the question Where a student has made a genuine attempt to respond to the question, assessors should score the response as ‘0’ (zero) where: The student has crossed out their whole response or The student’s response does not meet the assessment criteria to be awarded any marks Student Concern © VCAA Page 2 Foundation Mathematics MA103 – Assessment Guide 2025 Occasionally, assessors encounter a response that may raise concerns about the welfare of the student. Examples may include: suggestions or claims of abuse or neglect indications of distress, self-harm or suicidal tendencies threats of violence, harm, or criminal acts involving others. In such cases, assessors should assess the student work in accordance with the Assessment Guide and send the student script/item to be reviewed according to the instructions on the next page. Any matter of concern that an assessor believes requires urgent attention should be referred to the VCAA immediately via call to the VCAA Helpdesk: 1800 820 122. Sending student responses to review During marking assessors may identify student responses to be escalated for review by the Chief Assessor or to be noted by VCAA staff. The review categories are: Category Description Illegible response You are unable to read the student’s response. Incomplete student work The student appears to be missing part of their response or has indicated it continues in another area that is not attached as an attachment. Possible connection to student You recognise the student’s work. Please provide details. Student concern There is evidence of student distress. Technical Issue (VOSS Helpdesk) You are not able to continue scoring this exam or item due to a technical issue. Only use this category if you have contacted VOSS support on 1800 820 122. Below is a list of common issues that may arise, and how to respond to these: © VCAA Page 3 Foundation Mathematics MA103 – Assessment Guide 2025 Issue Evidence of student distress or concern. Note: Student concern does not include unfinished work or work that is off-task. The student’s handwriting is too faint to read, and you are unable to read and score the student response accurately. Action Assess the student response using the Assessment Guide. Send the student response for review, selecting the ‘student concern’ review category. Make every effort to read the student’s work. If unable to read the response, send the script for review, selecting the ‘illegible response’ review category. Note: Some student responses may include different handwriting or typed responses. This is usually due to Special Examination Arrangements and therefore does not need to be reported to the VCAA. The student’s response appears to be unfinished, or they have indicated their response continues on another page that is not attached. Refer to the Assessment Guide and score this as the student’s response, and send the student response for review, selecting ‘incomplete student work’ review category. The control of the mechanics of language is not sufficient to communicate a coherent response. Refer to the Assessment Guide and score this as the student’s response. You may contact the Chief Assessor for advice on how best to score the response. Responses in Languages other than English Unless otherwise stated, responses in a language other than English should not be awarded marks and should be scored zero (0). © VCAA Page 4 Foundation Mathematics MA103 – Assessment Guide 2025 Marking Guide Question 1 1a 500 10 50 Smallest volume 1.8 100 180 1b correct answer of 10 (units not required) 1A – for smallemst volume of 180 1A – for largest volume of 1200 OR IF BOTH VALUES INCORRECT Largest volume 12 100 1200 1c 1A – 1M – multiplication by 100 anywhere 1M – seeing a conversion of 6.6 billion cubic metres to 6600 GL OR 13449 GL to 13.499 billion cubic metres OR 6600 in the numerator/13499 in the denominator in a fraction calculation OR 13.499 in the denominator in a fraction calculation 1A – correct whole number percentage of 49% (percentage symbol not required) AI consumption: 6600 6.6 100% 100% 49.07.... 49% Percentage= 13449 13.449 © VCAA Page 5 Foundation Mathematics MA103 – Assessment Guide 2025 Question 2 2a Mean = 87.003 88 86.998 87.004 86.990 87.199 5 Piston diameters in tolerance range: 87.003, 86.998, 87.004 1A – correct mean of 87.199 (units not required) Value needed to 3 decimal places.
