Common questions

Does it teach how to intercept communications?
No. It explains what telecom and network records show, what they cannot prove, and the legal controls on interception. It teaches no technique for covert access.
Will it help me read a call record?
Yes. It walks through call records, cell-site evidence and IP addresses, with the common ways people over-claim what they show.
When can I take the final assessment?
When you have marked complete the units that are core on your path. The final draws its questions from those units. If you did not choose a role, every unit counts.
Is this legal advice?
No. The course teaches how the law and practice work. For a real case, follow your organisation's procedures and take advice from a qualified lawyer where you work.
Is this an official licence or certification?
No. LEA.Training is a private training provider. A course builds knowledge and readiness and ends with a Record of Completion. It is not a licence, a regulator's certificate or an accreditation, and it is not endorsed by any government agency.
Can I try it before I pay?
Yes. The first lesson of each course is open to read, with no sign-up.
How do I get a Record of Completion?
Finish the lessons, then pass the course’s final assessment with 70% or more. Your Record carries a number and a QR code that anyone can check on the verify page. It shows only your name (or initials), the course, the date and its status.
How long do I keep access?
Paid access lasts 12 months from the day you buy. You can study at your own pace and come back to any lesson during that time. Your Record of Completion stays verifiable after access ends.
Who sells the course, and how is tax handled?
In the Global edition the seller is Vanaranya LLC. Tax, where it applies, is calculated at checkout from your billing country.
Can I buy seats for my team?
Yes. Agencies, firms, colleges and companies can buy seats, assign the right path for each role and see progress and results. Larger teams get a discount. See For organisations.
