As you come to your final year in NCEA, there are three general topics within the science stream. These are chemistry, biology, and physics. Some schools offer other science subjects such as environmental science. The faithful three, however, are available in all schools and provide the foundations for you to go on to higher education.
Key Takeaways
- NCEA Level 3 Chemistry has 28 available credits across seven achievement standards, although individual schools may offer only a selection of them.²
- Four standards are internally assessed and three are externally assessed, with the three external Chemistry standards worth 15 credits altogether.²
- Level 3 Chemistry builds on earlier knowledge, particularly Level 2 Chemistry, so revisiting weaker topics can make exam preparation easier.³
- Chemistry is an approved University Entrance subject, with students needing 14 Level 3 credits in each of three approved subjects to meet the approved-subject component of UE.⁵
- Past papers, assessment schedules and exemplar answers are useful for learning how NZQA questions are structured and what is expected at Achieved, Merit and Excellence.²
What to Expect from NCEA Level 3 Chemistry
Due to the breadth of content knowledge required, once you pick a science pathway, it can be difficult to switch to a different course later in your education. This is because these subjects require you to have learnt the knowledge from the year before. The same level of physics is not transferable to the same level of chemistry. There would be too many gaps, making a challenging subject even more difficult.
If you are an international student, there may be differences between how you learnt chemistry at your old school and at your new school. There is no need to panic; the best thing to do is to speak to your chemistry teacher so they can help you identify any potential issues you may have in the course.
This complete guide to NCEA Level 3 Chemistry explains the chemistry syllabus, how to study for your internals and externals, the best way to approach chemistry questions, and the advantages of using past exam papers. It gives a summary of the different aspects of Level 3 Chemistry in the New Zealand education system. For more in-depth information, check out our different guides.
Demystifying the NCEA Level 3 Chemistry Syllabus
While this may be your final year within the NCEA system, it may be the first time you have seen the link between the New Zealand Curriculum and NCEA. For those who are not quite sure what these two things are, the New Zealand Curriculum is a document that outlines what students need to learn each year in the New Zealand education system.
NCEA Level 3 students in 2026 are still assessed using the existing Level 3 achievement standards. The Government has since confirmed that NCEA will be replaced by new senior secondary qualifications, with NZCE rolling out for Year 12 in 2029 and NZACE for Year 13 in 2030.¹
| Standard | What It Covers | Assessment | Credits |
|---|---|---|---|
| 91387 | Carry out an investigation in chemistry involving quantitative analysis | Internal | 4 |
| 91388 | Demonstrate understanding of spectroscopic data in chemistry | Internal | 3 |
| 91389 | Demonstrate understanding of chemical processes in the world around us | Internal | 3 |
| 91390 | Demonstrate understanding of thermochemical principles and the properties of particles and substances | External | 5 |
| 91391 | Demonstrate understanding of the properties of organic compounds | External | 5 |
| 91392 | Demonstrate understanding of equilibrium principles in aqueous systems | External | 5 |
| 91393 | Demonstrate understanding of oxidation-reduction processes | Internal | 3 |
What is interesting about this document is that it does not explicitly state what content all students must learn, but rather what skills they need. This makes it a rare and very modern guiding educational document. It also explains why you and someone at a different school may not be learning the same thing at the same time.
The New Zealand Curriculum is skill-based, so there are certain things students are expected to be able to do at each level. In primary school, students do one level of the curriculum over two years; however, when they enter secondary school, they are expected to do one level in one year.
This is why students must enter secondary school at the required level; otherwise, the progression of the required work becomes too much, as they start on the back foot, making it hard to catch up.
When you enter NCEA, the National Certificate of Education is used to assess how much you have learnt. In Chemistry, there are specific assessments in which students must be taught certain content.
available credits across seven achievement standards, although individual schools may offer only a selection of these standards.²
These assessments will either be completed internally (within class time and possibly in your own time) or externally (an exam at the end of the year in which all Chemistry students across New Zealand sit at the same time). For more information, check out our guide that explains the Level 3 syllabus in more detail.
Chemistry credits contribute towards NCEA Level 3, but Chemistry alone does not provide enough credits for the qualification. Students need 60 credits at Level 3 or above, plus 10 Literacy or Te Reo Matatini credits and 10 Numeracy or Te Pāngarau credits. The literacy and numeracy requirements only need to be met once across NCEA.⁴
NCEA Level 3 Chemistry Study Guide
The level required to pass assessments is raised each year. In general, the difference between the Level 1 and Level 2 marking schedules is often considered to have the biggest jump. In chemistry, a strong understanding of the Level 2 syllabus is necessary to gain a good grasp of the theories, concepts, and ideas in Level 3, with NZQA specifically assuming prior Level 2 organic chemistry knowledge for the Level 3 organic compounds standard.³
Chemistry is an approved subject for University Entrance (UE). To meet the approved-subject component of UE, students need at least 14 Level 3 credits in each of three approved subjects.⁵ All seven current Level 3 Chemistry achievement standards, 91387 to 91393, are included on NZQA’s approved Chemistry list.⁶
Whether you are looking to gain higher qualifications within the domain of chemistry or not, it is always a great idea to learn how to study more efficiently. While our guide to studying for Level 3 Chemistry may focus on a single subject, the skills and study tips are transferable. So if you are also studying biology, physics, history or any other subject, you can use the same ideas t
Level 3 Chemistry Assessment at a Glance
When revising for internal chemistry assessments, there are elements of research, revision, writing, and recording you will need to master. When it comes to research, note down where you got the information from and check its reliability.
Nothing like a bit of internet sleuthing to start you off in the right direction. Speak to your local librarian to help you find sources, and you can use Google Scholar. Google Scholar is free to use and enables you to use a search engine that is good for simple searches across a wide range of scholarly literature databases.
As external exams require you to answer questions without any external help, they offer more credits, and you need to prepare differently than for internal assessments. To succeed, you need a wide range of strategies to help you remember a lot of information.
Re-reading your notes is a good start, but you also need to interact with them. That can be done through flip cards, creating bullet-point notes, and asking rapid-fire questions with friends. You want to build pathways in your brain to different bits of information. To strengthen the pathways, you need to engage with the information regularly.
Revision Tips: How to Tackle NCEA Level 3 Chemistry Exam Questions
Understanding what you have to do and how to do it are skills you are being tested on. Reading comprehension is about being able to decode what is written, being able to make connections between the chemistry question and what you know, and your ability to think deeply about what you have read and understood of the topic related to the question.
These are not skills we are born with but things we must learn. A big part of reading comprehension is vocabulary knowledge and text comprehension. You have to know what the word means as well as understand the meaning when placed in a certain context. Across many languages, including English, words can change meaning depending on the words around them; for example, the word "peer": the article was peer-reviewed, and I really want to peer into that well.
The word has completely changed its meaning due to the sentence's context. In science, whether that be biology, chemistry, or physics, you need to have vocabulary knowledge; otherwise, you will come across words you don’t know and don't understand their meaning.
credits altogether.
| Standard | Exam Topic | What to Focus on |
|---|---|---|
| 91390 | Thermochemical principles and properties of particles and substances | Revise chemical structure, bonding, properties and thermochemical principles. Practise calculations and explaining the chemical reasoning behind your answers. |
| 91391 | Properties of organic compounds | Revise organic structures, properties and reactions. Level 2 organic chemistry knowledge is assumed, so revisit earlier material if you have gaps. |
| 91392 | Equilibrium principles in aqueous systems | Revise aqueous equilibria, acids and bases, equilibrium constants and relevant ions. Practise calculations as well as explaining changes to equilibrium systems. |
This is where our guide on NCEA Level 3 chemistry questions can help, as it gives you tips and strategies to learn the skill of breaking down questions. Breaking questions into sections also helps you ensure you have answered them fully, especially for merit and excellence questions, which can be pretty wordy.
What to Know Before Your Level 3 Chemistry Exams
NCEA Level 3 Chemistry Past Papers
One part of understanding NCEA is understanding the marking schedule. You don’t need don'ty to guess what the examiners are looking for, as the marking schedule is very clear. It can just be a little tricky to understand the keywords if you haven’t had experience decoding them.
Past exam papers can be incredibly helpful for two main reasons: you can use them to revise, and you can use them to understand the marking schedule better. Each of the three exam papers uses similar keywords, but how you demonstrate your knowledge is different. This is because the topics are not the same. However, the structure of your responses to the questions for each topic often overlaps.
Our guide on NCEA Level 3 Chemistry past papers explains where to find them, what to look out for and the best way to use them. It also examines some of the differences between achieved, merit and excellence across the three exam assessments. This can be very helpful when looking to improve your grade.
