The eJDS - Junior Data Scientist exam voucher costs Rs 64,900/= at induwara.lk, payable in Sri Lankan rupees by card or bank transfer. It is an official single-use voucher for the INE exam, not a practice test or a training course. The voucher is valid for 12 months from purchase. After payment our team confirms your order and sends the voucher code by email.
What this voucher is
The INE voucher for eJDS - Junior Data Scientist, with no currency conversion to work out. It is the exam fee itself — a single-use code you redeem when you book your exam with the vendor's testing provider. It is not a training course, a practice test bundle or a study guide.
Each voucher is valid for 12 months from the date of purchase, so you can book the exam when you are ready rather than the day you buy.
Who sits this exam
eJDS - Junior Data Scientist is aimed at SOC analysts, network engineers and anyone moving into a security role. It is an entry-level exam, so there is no formal prerequisite — it is a reasonable first certification. Sri Lankan banks, ISPs and BPO firms hire against named security certifications, and the exam fee is usually the part that stalls people.
Why buy it here
Vendor exam fees are quoted in US dollars, which means the rupee price you actually pay depends on your card's rate on the day and whatever your bank adds on top. Here the price is fixed in rupees — Rs 64,900/= — so what you see is what leaves your account.
You can pay by card through PayHere, or by direct bank transfer if you would rather not put an exam fee on a card. Both are confirmed by us before anything is sent.
How delivery works
Delivery is handled by a person, not a script. Once your payment is confirmed, our team contacts you and sends the voucher code to the email address on your order. That usually happens the same day, and you will hear from us either way — if there is any delay sourcing a particular voucher, we tell you rather than leaving the order sitting.
If you need an invoice for an employer or a training budget, say so when you order and we will issue one against the order number.
Exam at a glance
Prerequisites
None enforced — INE states 'Anyone can attempt the certification exam'. It says the exam 'is best suited for candidates who already have experience with Python and seek to formalize their knowledge in data operations, statistical reasoning, and machine learning applications'. Commercial requirement: 'To take the eJDS exam, you'll need both an INE subscription and an exam voucher.' INE's recommended preparation is what the page calls the Data Scientist Learning Path.
Sat through
INE — online, managed from INE's Certifications Dashboard. INE states results 'are on an auto-graded system' and 'will be delivered within a few hours after completing the exam', with a score report showing performance metrics in each section. No test centre.

What you get, and what happens next
What you get
One official single-use exam voucher for eJDS, eJDS - Junior Data Scientist, covering the exam fee in full. It is a code, not a study course and not a practice test. There is nothing physical to ship and no delivery charge.
When it arrives
Emailed to the address on your order once we have confirmed the payment, by a person rather than automatically. In practice that is usually the same day and almost always within one working day. If sourcing a particular voucher is going to take longer, we tell you rather than leaving the order sitting.
How long it stays valid
12 months from purchase. Book and sit the exam before it expires, a code that has simply run out of time cannot be replaced, so do not buy months ahead of when you plan to use it.
How you redeem it
Redeemed inside INE's own certification dashboard. There is no test centre and no separate booking to make. The code unlocks the attempt on your account.
If the code does not work
If the vendor rejects it when you try to redeem it, tell us straight away and we replace it or refund you in full. Contact us before the voucher’s own expiry date.
If you do not pass
A voucher covers one attempt. A retake needs a new voucher, and the vendor, not us, sets how long you must wait before sitting the exam again. Check the vendor’s retake policy before you book.
Changing your mind
Full refund for any reason as long as we have not yet sent the code, including if you realise you have ordered the wrong exam, which is easy to do when codes look alike. Once the code has been sent it cannot be refunded, because the code is the product and it is single-use. Refunds & delivery in full.
What the exam covers
Data Analysis with pandas and NumPy in Python (30%)

Describing classification algorithms, and the construction, advantages and limitations of decision tree models
Where it leads
Junior data scientist and data analyst roles — INE names aspiring data analysts and data scientists and software professionals among its audience. In the Sri Lankan market it is most useful to graduates and self-taught Python developers targeting the data and analytics work that the IT and BPO export sector has been expanding into, where a vendor-assessed credential helps in the absence of prior commercial data experience.
Sitting this exam in Sri Lanka
Sri Lanka's IT and BPO export sector has been adding data and analytics work alongside its traditional software delivery, and the eJDS is one of the few vendor-assessed entry credentials aimed at that first data role rather than at an academic audience. Because 90% of the exam is data analysis, statistics and machine learning rather than programming syntax, it tests reasoning that a computing degree here may only have covered in passing. It is taken online with no test centre booking, and INE requires a subscription alongside the voucher. Buyers should be clear that this is a data science credential, not a cybersecurity one — INE publishes it under its data science range.
Where these details come from
Every fact on this page was read off the vendor’s own documentation. Vendors change exam content, pricing and retirement dates without notice, so check these before you book.
No. It is a data science certification. INE publishes it under its data science range at ine.com/certifications/data-science/, separate from the INE Security catalogue that the eJPT, eCPPT and the rest belong to, and INE's launch announcement positions it as a data science credential. If you are looking for an entry-level security credential, the eJPT is the equivalent first rung.
How much of the exam is actually Python programming?
Only 10%. Advanced Python programming is the smallest domain. The other 90% splits evenly at 30% each across data analysis with pandas and NumPy, fundamentals of statistical analysis, and machine learning. Strong Python alone will not carry the exam — the statistics section is weighted just as heavily as the coding.
Do I need a data science background before sitting it?
No formal prerequisite. INE states that anyone can attempt the exam, and that it is 'best suited for candidates who already have experience with Python and seek to formalize their knowledge in data operations, statistical reasoning, and machine learning applications'.
How new is this certification?
INE announced it on 28 October 2025, which makes it the newest exam in this catalogue. That is worth knowing for two reasons: the syllabus reflects current tooling, and there is very little third-party preparation material around it yet, so INE's own Data Scientist Learning Path is effectively the primary resource.
Does INE publish a pass mark, duration or question count?
No. INE's page sets out the four domains and their weights, the retake terms and the validity period, but none of the exam logistics. We would rather tell you that than invent figures. What is confirmed is that grading is automatic and results arrive within a few hours.
What machine learning content is assessed?
Machine learning is 30% of the exam. INE's objectives name implementing basic machine learning algorithms for predictive modeling, describing the principles and workings of different classification algorithms, and describing the construction, advantages and limitations of decision tree models — so conceptual understanding is tested, not only the ability to call a library function.
Do I need an INE subscription as well as the voucher?
Yes. INE states: 'To take the eJDS exam, you'll need both an INE subscription and an exam voucher.' A bundle pairing the voucher with three months of access is one of INE's routes. Include it in your total cost.
What does the eJDS voucher cost in Sri Lanka?
Our eJDS voucher is Rs 64,900/= in rupees, which avoids needing a card enabled for US-dollar transactions. INE does not publish a US-dollar price on the certification page.
