DISC Assessment Alternatives: The Best DISC Tests and What to Try Instead

If you searched for Truity DISC, here is what Truity's own test page says. It is a 38-question assessment that takes about 5 minutes, and you can see a summary without paying or registering. You get a primary DISC style and scores on the other three. A fuller report is available for a fee, and Truity offers the same test to teams through its Truity@Work platform.

The main thing to know is the naming. Truity's four styles are Drive (control, power, and assertiveness), Influence (people, interaction, and communication), Support (patience, thoughtfulness, and harmony), and Clarity (structure, organization, and correctness). Truity credits the model to William Moulton Marston, but the S and C labels differ from the Steadiness and Conscientiousness used by Wiley's Everything DiSC, so don't expect a Truity result to map one-to-one onto a DiSC report from work.

Truity also publishes a technical document for the test. For a free, quick, individual DISC result, it is the easiest place to start.

There is no single official DISC. The model is Marston's, and the best-known assessments come from different companies with different spellings, labels, and ways of buying.

Everything DiSC (Wiley)

Wiley owns DiSC and Everything DiSC. Its history traces the first DiSC assessment to John Geier's Personal Profile System in the 1970s, published by Performax, which later became Inscape Publishing and is now part of Wiley. Everything DiSC launched in 2007. Wiley describes its assessments as computer-adaptive and points organizations to authorized partners who run facilitated sessions, in versions such as Workplace, Management, Agile EQ, Productive Conflict, Work of Leaders, and Sales. Its letters stand for Dominance, Influence, Steadiness, and Conscientiousness, and Wiley writes the four styles as D, i, S, and C.

TTI Success Insights

TTI's DISC measures Dominance, Influence, Steadiness, and Compliance. Organizations use it through TTI or certified partners, and TTI pairs it with other measures, such as motivators, emotional intelligence, and competencies, in combined reports.

Covered above: free, 38 questions, and its own labels for S and C.

The best DISC assessment test for you comes down to context. If your company already runs Everything DiSC or TTI workshops, use that version so your results match your colleagues'. If you are on your own and curious, a free test like Truity's is enough to learn your style.

DISC describes how you behave, especially at work: how fast you move, how much you push, how you deal with people and rules. TTI's own description is that it covers how you prefer to act, communicate, and make decisions, and that it does not measure intelligence, aptitude, values, or mental health.

If you have taken DISC, parts of the Big Five will feel familiar. The outgoing, persuasive side of Influence overlaps with extraversion, the patient, cooperative side of Steadiness with agreeableness, and the careful, rule-minded C with conscientiousness. The difference is that a Big Five test scores each trait on its own scale, and it adds neuroticism and openness, which DISC does not frame as styles.

The bigger gap is values. Two people with the same D style can want completely different things from that drive. Opinion DNA scores personal values such as achievement, power, and security, alongside moral foundations and thinking style, so you can see what the behavior is in service of.

Most DISC is bought for teams, so it is fair to compare alternatives on team use.

• •CliftonStrengths, from Gallup, is a 30-minute assessment of paired statements that ranks 34 talent themes. It suits teams that want to talk about strengths.
• •A Big Five test gives each person continuous trait scores, which is more precise than a style and less tied to the workplace.
• •Opinion DNA compares people across all 48 dimensions. Its team product and co-founder comparison show where a group's values and thinking styles line up or pull apart.

Use DISC when the goal is a shared language for working styles on one team, and pick the publisher your colleagues already use. Use a broader assessment when the goal is understanding yourself: why you react the way you do, what you care about, and how you reason under uncertainty.

Opinion DNA is built for the second case. It measures 48 dimensions in 179 questions, takes about 10 to 15 minutes, and comes with an AI-generated report covering personality, values, meta-thinking, career, and relationships. It costs $47 once, with a 30-day money-back guarantee. Start with the full assessment.
