Lanterna's ESS teachers and specialists give one-to-one online lessons in IB Environmental Systems and Societies at SL and at the HL first examined in 2026, covering the Paper 1 case study you meet unseen, Paper 2's data questions and your own investigation. UK students book evenings or weekends on UK time from £58 an hour. Further down: which UK degrees accept ESS as a science, and which don't.
Say whether you take SL or HL, which other sciences are on your timetable and whether the investigation or the exams need the time, and we suggest an ESS tutor who teaches the current syllabus.

IB ESS TutorFormer DP coordinatorImperial College London
I’m an IB Diploma graduate and former IB DP Coordinator with over a decade of international teaching experience in Singapore, Japan, and the U.S. I completed my undergraduate degree at Imperial College London and my master’s at University College London (UCL) before earning a Distinction-awarded M.Ed. in Educational Leadership and Policy from the University of Adelaide. Since 2017, I have served as an IB Geography Examiner, marking Internal Assessments and Paper 3 exams, and attending standardization meetings with examining heads and lead examiners.
I'm Olympia, a French and English IB tutor! I completed the IB in 2023 with 40 points, and I am now studying Politics, History, and Finance at Sciences Po Paris with a year at Cambridge. I achieved a 7 in History HL, 7 in French A SL, 7 in ESS, 6 in Economics HL, and 6 in English A HL- these are all topics that I tutor in. In our tutoring sessions, I adapt to what needs the most practice: exams, the IA, terminology, structuring essays, etc. I have been tutoring IB students for 4 years now, and I also tutor young professionals online. I am a firm believer that 7's in the IB are achievable with the right strategy and study method, which we can work on together. Outside of tutoring, I still study at university and enjoy playing tennis and rowing!
I'm Sophie, I graduated with 40 IB points in 2014. After studying at 5 universities across 3 countries (starting with Leiden University) in the Netherlands, I became a Geography and Environmental Systems and Societies teacher at a Dutch international school. I started my career as a schoolteacher in 2017, and more recently have also become a Careers Counsellor for IB students. I have tutored hundreds of students since then, mostly in maths and sciences but also in languages and of course my own exam subjects. I am great at integrating exam practice into my lessons so students can smash their exams. When I'm not tutoring, I like acting, dancing and baking.
I'm Greta, an IB graduate with 43 points who is about to finish a BSc at the London School of Economics (LSE) in International Relations and History. I achieved 7s in History HL (including all 7s on paper 1, 2, and 3), French Language and Literature HL, Environmental Systems and Society (ESS) as well as an A in TOK. I have been tutoring IB students for 3 years but I also have prior experience teaching non-IB syllabuses. I focus on helping students master the exam strategies that proved effective during my own IB experience. Additionally, I support students throughout the IA process, from topic selection to final submission. Outside of tutoring, I am a volunteer English teacher to forcibly displaced people in a refugee center.
I’m Annha, an experienced IB educator and examiner specializing in Biology (HL/SL) and Environmental Systems and Societies (HL/SL). With over 8 years of teaching experience, I’ve had the privilege of guiding countless students to achieve their academic goals from earning 6s and 7s in IB exams to producing top-tier Internal Assessments (IAs) and Extended Essays (EEs) (as I work as a reviewer for Clastify as well). I hold an MPhil in Food Safety and Quality Management and a Bachelor’s in Biotechnology, and I’m a Certified IB Educator (Biology and ESS Category 2). Since becoming an IB DP teacher in 2021, I’ve also taught at the MYP level, helping students build strong scientific foundations that prepare them for the Diploma Programme and beyond. My tutoring style is student-centered and inquiry-based. I focus on simplifying complex ideas, connecting them to real-world examples, and developing core IB skills such as critical thinking, data analysis, and structured writing. I love creating interactive, visually engaging lessons that make learning science both meaningful and enjoyable. Outside the classroom, I’m deeply passionate about environmental science and sustainability, and I enjoy writing, photography, exploring nature and playing guitar. My students describe me as approachable, patient, and encouraging — a teacher who makes learning not just effective, but genuinely enjoyable.
I’m Sitwat, an experienced IB Biology and Science educator with a strong academic foundation in Zoology and Botany. I hold a Master of Education from Northwest Missouri State University and have taught in international schools across South Africa, Vietnam, Pakistan, and the UAE. This global experience has strengthened my ability to adapt to diverse curricula, learning styles, and academic expectations. I teach IB Biology (SL & HL), Environmental Systems and Societies (ESS), Chemistry, general Science, and MYP Science. Over the years, I have supported students from varied academic backgrounds, helping them build conceptual depth while refining exam performance skills. I have supervised Extended Essays and provided structured guidance for Internal Assessments, ensuring alignment with IB criteria in research design, data analysis, evaluation, and scientific communication. I also facilitate collaborative science projects that promote inquiry-based learning, critical thinking, and interdisciplinary understanding. My tutoring approach is structured, analytical, and student-centred. I begin with a focused diagnostic review to identify gaps, then break complex biological processes into clear, logical frameworks. I emphasise precise use of IB command terms, markscheme analysis, and data interpretation skills so students can convert understanding into high-scoring responses. Each session is tailored, interactive, and strategically aligned with assessment objectives. I aim to develop independent scientific thinkers who approach challenging concepts with confidence, clarity, and academic rigour.
Only for some environmental degrees. Manchester's MEnvSci Environmental Science names ESS among the subjects it treats as science or mathematics for 2027 entry, next to Biology, Chemistry, Geography, Physics and Mathematics; no medicine or engineering requirement we have read accepts ESS in place of Biology, Chemistry or Physics.
The contrast shows inside one university. Manchester's MBChB Medicine asks for Chemistry or Biology plus another science from Chemistry, Biology, Physics, Psychology or Mathematics, and ESS is not on that list. Engineering offers name HL Maths and Physics: Oxford's asks for 7s in both, as our Physics page explains, and the medical schools' subject rules are on the Chemistry page.
So the time to check is at subject choice or early in DP1, while there is still room to change. If ESS is your only science and medicine, engineering or a physical science might be on your list, ask your IB coordinator about adding Biology, Chemistry or Physics. Families also considering Germany or Switzerland should know that neither country counts ESS as a science at all.
Picking up a science late
A student who adds Biology or Chemistry after DP1 has begun has topics to catch up on. A Biology tutor can cover what the class has done so far, alongside ESS lessons with the same or a different tutor.
The course
How the redeveloped ESS course is assessed
The current ESS course was first taught in 2024 and first examined in May 2026, when an HL option appeared for the first time; the IB's update notes list the changes. Systems, perspectives and sustainability run through all of it.
Eight topics. The foundation unit comes first, then ecology; biodiversity and conservation; water; land; atmosphere and climate change; natural resources; and human populations and urban systems.
Paper 1. Built on a resource booklet about a place or issue you have not studied; the questions ask you to apply the course to it and weigh its evidence.
Paper 2. Opens with short questions on graphs, tables and figures and ends with essay-length answers that link topics across the syllabus.
Investigation. One study of your own choosing, scored against criteria worth 30 marks whichever level you take.
The hardest part to practise alone
Paper 1 asks you to weigh unfamiliar evidence quickly. Timed attempts with a tutor's marking, done well before the papers in late April to mid-May 2027, show where an answer described a source instead of evaluating it.
SL or HL
ESS at Standard and Higher Level
In May 2025, when ESS was still an SL-only course, the worldwide mean grade was 4.3. The HL level adds judgement about policy and values to every topic, and its short exam history means specimen papers do much of the work in revision.

Reviews
What IB families say about their tutors
“…helped me understand the subject (IB Math AA SL) in much more depth and has helped me achieve two grades higher than my predicted. Eleni took the time needed to explain everything properly and we did many practise questions so I could be best prepared for my exams.”
HanneloreMathematics: Analysis & Approaches
“The classes are open and very much adapted to my individual needs. Finally, I am not afraid to ask a question, as I know that my tutor will explain the material to me in the best possible way. After only 2 classes I have managed to improve my physics grade from a 6 to a 7, but more importantly, I have managed to understand the material, which I think is the most important point. I cannot recommend Lanterna highly enough.”
“Personalised classes, tailored to your…”Physics
“When we needed help urgently, they delivered. When we needed to adapt the plan, they adapted with us. My son passed his IB Diploma and we couldn’t be prouder. Lanterna played a real part in that success and I would recommend them without hesitation to any parent navigating the IB journey.”

Choosing IB Higher Level vs Standard Level subjects is crucial. Learn five expert considerations on workload, university requirements, and IB grading to make the right choice.
Which ESS tutor suits a student taking the new HL course?+
One who already teaches the redeveloped course, first examined in May 2026, including the HL lenses of environmental law, economics and ethics. HL has few past papers so far, so Lanterna tutors draw on specimen material and their own questions. Tell us the level at the consultation and we match accordingly; SL students stick to SL content.
Is ESS tutoring worthwhile if my child wants to study environmental science at university?+
It can be, because at least one UK course counts ESS as a science: Manchester's MEnvSci Environmental Science lists it beside Biology, Chemistry, Geography, Physics and Mathematics. A stronger ESS grade then helps twice, with the subject condition and with the points total. Check each course on your shortlist, as the rule above is Manchester's own.
We need help with ESS and Geography. Do we need two tutors?+
Not always. ESS and Geography share case-study thinking and fieldwork methods, so a tutor who teaches both can keep your child's examples consistent; ask for that pairing at the consultation. Where levels or weekly hours rule out one person, we suggest two.
How can a tutor help with my child's ESS investigation without breaking IB rules?+
By coaching, not writing. A tutor can help turn a broad interest into a question that local data can answer, talk through sampling and fair methods, and explain how the 30 marks are awarded. Collecting the data, analysing it and writing the report stay with the student; our IA guide and the 40 ESS investigation ideas are good places to start. Internal deadlines vary by school, so book help well before yours.
When should ESS revision lessons start before the May 2027 exams?+
Plan around the Easter holidays. The written papers fall between late April and mid-May 2027, roughly two weeks after many local-authority Easter breaks end, so the holiday is the last long stretch for timed case-study practice. Independent schools set their own dates; check your school's calendar.
What do online ESS lessons cost in the UK?+
From £58 an hour, one-to-one, priced in pounds; larger packages bring the hourly rate down (see prices). ESS students we have tutored rose from an average of 4.2 to 5.6, a group average that can't be promised to any one student.
