The Certifyforce Tableau Desktop Foundations study guide covers the official Salesforce Tableau Desktop Foundations exam outline in 26 units across all 4 exam sections, one unit per exam-guide topic. The exam itself has 40 scored questions plus 5 unscored, a 70-minute limit and a 48% passing score, and its largest section is Exploring and Analyzing Data at 37%. Every unit is verified against official Salesforce documentation, cites its sources, and links to the practice questions that test it. Last updated October 29, 2026.
Focused on Tableau Desktop fundamentals: connecting to data and choosing live or extract connections, the data model and field properties, building basic charts, filtering, sorting and grouping, calculations and analytics on a worksheet, sharing insights with dashboards and stories, and core concepts such as dimensions and measures and discrete and continuous fields.

Connecting to and Preparing Data
23% of the exam- Live connections and extracts~8 minHow a live connection queries the source while an extract is a saved .hyper copy, when each fits, how to build an extract in the Extract Data dialog, and which settings (filters, hidden fields, Number of Rows, incremental refresh, storage) shape it.
- Relationships versus joins in the data model~8 minThe logical layer (relationships, or noodles) versus the physical layer (joins and unions), how a relationship keeps tables at their own level of detail while a join merges them up front, and when a join is still the right choice.
- Field names, aliases and data types~8 minHow renaming a field differs from aliasing its members, why Aliases only appears for discrete dimensions, and how to read and change a field's data type from its icon, before you create an extract.
- Saved data sources and multiple connections~8 minWhat a saved .tds stores (connection information plus calculations, groups, sets, bins and default field properties) versus a packaged .tdsx, how to reuse it from the Connect pane, and how a second connection in one data source enables a cross-database join.
- Join types and unions in the physical layer~8 minHow to open a logical table to reach the join canvas, what inner, left, right and full outer joins keep, and how manual and wildcard unions stack same-structure tables, including Merge Mismatched Fields and the Sheet and Table Name fields a union adds.
- Geographic roles and default field properties~7 minHow to assign the right geographic role (Airport, City, State/Province, ZIP Code/Postcode, Latitude, Longitude) from a field's data type icon and what Tableau generates, and how Default Properties set a field's number format, date format, aggregation, color, sort and comment once for every new view.
Exploring and Analyzing Data
37% of the exam- Bar, line and scatter plot charts~8 minHow the fields on Rows and Columns decide the chart: a dimension and a measure make bars, a date and a measure make a line, two measures make a scatter plot. Covers the Mark Type drop-down, stacked bars with Color, continuous monthly lines, Detail for more scatter marks and trend lines.
- Groups and hierarchies for organizing dimensions~7 minCombine dimension members into groups from the Data pane, from headers or from marks, add an Other group, and organize fields into hierarchies you drill with + and -. Covers the Desktop versus web paths and what Remove Hierarchy really removes.
- Sorting, reference lines and totals~8 minSort a view by clicking, dragging or the Sort dialog (Data Source Order, Alphabetic, Field, Manual, Nested), clear sorts, add a reference line to a continuous axis with the right computation and label, and show grand totals and subtotals where readers need them.
- Symbol, filled and density maps~8 minDouble-click a geographic field to start a map, then turn it into a proportional symbol map (measure on Size), a filled map (Map mark type, measure on Color) or a density map (Density mark type over many overlapping points), and know which data each one suits.
- Combined axis and dual axis charts~7 minThree ways to show two measures together: separate axes, a combined (blended) axis built from Measure Names and Measure Values, or a dual axis with two independent scales in one pane. Covers where to drop the measure, Synchronize Axis, and per-measure Marks cards for bar-and-line combo charts.
- Crosstabs and highlight tables~7 minHow to show exact values in a text table (crosstab) and shade them in a highlight table: dimensions on Rows and Columns, a measure on Text or on Color with Square marks, and how a diverging palette and Use Full Color Range change the shading around zero.
- Fixed, dynamic and combined sets~8 minSets define a subset of a dimension's members: dynamic sets from the Data pane (General, Condition and Top tabs) recompute as data changes, fixed sets from selected marks keep their members. Covers In/Out mode, set controls, combined sets and when to pick a group, a set or a filter.
- Dimension filters, filter cards and date filters~8 minFilter a view with Keep Only and Exclude on marks and headers, the Filters shelf dialog and filter cards (modes, Include or Exclude Values), and pick the right date filter: relative dates, a range of dates or a discrete date level such as one quarter of every year.
- Quick table calculations, bins and histograms~7 minApply a quick table calculation to a measure in the view (Running Total, Rank, Percent of Total, Year over Year Growth and the rest), recognize the delta symbol, adjust it with Edit Table Calculation, and build histograms from bins: Create > Bins, Size of bins, Show Me and continuous bins.
- Calculated fields and when to use parameters~8 minWrite string, date and arithmetic calculated fields in the calculation editor (+ for concatenation, STR, DATEADD, DATEDIFF, DATEPART), know how a new calculated field lands in the Data pane, and decide when a parameter, a single workbook-wide value used in calculations, filters and reference lines, fits a requirement.
Understanding Tableau Concepts
15% of the exam- Dimensions and measures in the Data pane~7 minWhat dimensions (qualitative fields that group the data) and measures (quantitative fields that get aggregated) contain, how Tableau assigns each role when it connects, how to read the role from a pill, and how to convert a misclassified number into a dimension.
- Discrete headers, continuous axes and date parts~7 minBlue discrete fields create headers and categorical colors, green continuous fields create axes and quantitative color legends; how to convert between them, which fields can't be continuous, and why a discrete MONTH date part differs from a continuous month value.
- Default aggregation and level of detail~8 minWhy a measure lands in the view as SUM, how to change its aggregation for one view or for every view, which aggregations a dimension accepts, and how each dimension you add splits an aggregate into more marks while a second measure leaves the level of detail alone.

How does the study guide map to the official Tableau Desktop Foundations exam guide?
There is one unit per topic in the official exam guide, grouped under its 4 weighted sections: Connecting to and Preparing Data (23%), Exploring and Analyzing Data (37%), Sharing Insights (25%), Understanding Tableau Concepts (15%). Each unit quotes the exam objective it covers word for word.
How do the practice questions link to the study guide?
Each unit lists the reviewed practice questions that test it (152 questions are linked across the guide), so you can read a topic and practice it in one click. After a practice exam, every missed question links back to the unit that teaches it.
