Module One: Getting Started with Tableau
Students begin by understanding what Tableau is and how it fits into the broader world of data analytics. This module covers the Tableau product family — Desktop, Public, Server, and Cloud.

Module Two: Connecting to Data and Preparing It in Tableau
Real Tableau work starts with connecting to data. Therefore, this module teaches students how to connect Tableau to multiple data sources. They link to Excel files, CSV files, SQL databases, Google Sheets, and web-based data. Furthermore, students learn how to use Tableau’s built-in data preparation tools, including joins, unions, pivots, and data interpreter to clean and shape their data before they start building visualizations.
Moreover, students practice working with live and extract connections, understanding the difference between querying data in real time and using a saved, faster local copy. Additionally, they learn how to create relationships between multiple tables in Tableau’s data model, a feature that mirrors the relational database skills they already know. As a result, every student finishes this module knowing exactly how to bring clean, reliable data into Tableau from any source they encounter on the job.
Module Three: Building Core Visualizations
With data connected and clean, students start building charts. This module covers all the core visualization types that every Tableau user must know. Students create bar charts, line graphs, scatter plots, pie charts, heat maps, tree maps, and geographic maps. Furthermore, they learn when to use each chart type, a critical skill that separates good data communicators from great ones.
Moreover, students study the Show Me panel, Tableau’s intelligent chart recommendation tool and learn how it chooses the right visualization based on the data types selected. Additionally, they practice formatting their charts professionally, using colors, labels, tooltips, and reference lines to make their visuals clear, clean, and compelling. As a result, students build a strong visual library of chart types they can use confidently in any future dashboard project.
Module Four: Calculated Fields and Table Calculations
Calculations are what turn basic charts into powerful business insights. Therefore, this module teaches students how to create calculated fields in Tableau. They write formulas using Tableau’s calculation editor to create custom metrics such as profit margins, growth rates, customer lifetime value, and market share percentages. Furthermore, students learn how to use Tableau’s built-in functions across string, number, date, and logical categories.
Moreover, students are introduced to table calculations, dynamic computations that reference other values in the visualization itself. They learn how to calculate running totals, percentage of total, rank, and moving averages using table calculations. Additionally, the Tableau Help documentation is used as a live reference throughout this module. As a result, students leave knowing how to calculate virtually any business metric inside Tableau without ever writing a line of code.
Module Five: Building Interactive Dashboards and Stories
Dashboards bring everything together. Consequently, this module is where the course truly comes alive. Students learn how to combine multiple charts onto a single Tableau dashboard. They set up filters, actions, and parameters that make dashboards interactive and dynamic. Furthermore, students study layout best practices how to arrange visuals, use containers, and design dashboards that work beautifully on both desktop and mobile screens. Every dashboard they build is published to Tableau Public for the world to see.
Moreover, students learn how to build Tableau Stories, a series of dashboard views that guide the audience through a data narrative step by step. Additionally, they practice presenting their dashboards to the class explaining their design decisions and the business insights their data reveals. As a result, every student graduates from this module with both the technical skill to build impressive dashboards and the communication skill to present them with clarity and confidence.
