The Tableau Desktop Specialist has four domains with official weightings. This is a plain-English summary; the official Tableau exam guide is authoritative. The credential was renamed to Tableau Desktop Foundations in 2025, but the domains below are unchanged.
| # | Domain | Official weight |
|---|---|---|
| 1 | Connecting to & Preparing Data | 25% |
| 2 | Exploring & Analyzing Data | 35% |
| 3 | Sharing Insights | 25% |
| 4 | Understanding Tableau Concepts | 15% |
1 - Connecting to & Preparing Data (25%)
Connecting to file and server data sources, the data source page, setting data types, and combining data with joins and unions. Knowing when to join (row level), union (stack rows) or blend (link separate sources) is core.
2 - Exploring & Analyzing Data (35%)
The largest domain: marks and the Marks card, Show Me, sorting and filtering, groups and sets, basic calculations and table calculations, and maps. Most of the exam’s hands-on questions live here.
3 - Sharing Insights (25%)
Building dashboards and stories, formatting, and publishing or sharing your work. A full quarter of the exam.
4 - Understanding Tableau Concepts (15%)
The foundational vocabulary: dimensions versus measures, discrete versus continuous (blue versus green pills), aggregation, and how Tableau organises a workbook.
