Choose live online for the best balance of flexibility and mentor interaction, self-paced if your schedule is unpredictable and you're disciplined about finishing, classroom if you learn best with in-person practice and networking, and on-site if you're training a team together as an organization.
The four delivery modes compared
All four modes cover the same certification syllabus at Sigma Consulting Services, the difference is pacing, interaction and cost, not content depth.
| Live Online | Self-Paced | Classroom | On-Site (Corporate) | |
|---|---|---|---|---|
| Instructor interaction | Real-time, scheduled sessions | None (e-books/video) | In-person, real-time | In-person, real-time |
| Schedule flexibility | Fixed session times | Fully flexible | Fixed session times | Set by your organization |
| Best for | Working professionals wanting live Q&A | Self-motivated learners with unpredictable schedules | Learners who prefer in-person practice | Teams training together |
| Typical cost | Standard course fee | Often the same or lower | Standard + venue costs where applicable | Custom corporate quote |
Frequently asked questions
Is a self-paced certificate viewed differently by employers?
What matters most to employers is accreditation and whether you completed a real project, not the delivery mode. That said, live formats make it easier to get mentor feedback on your project as you go.
