Overview
The GreyScale (TGS) is an advanced psychometric assessment designed to empower recruiters with deeper insights into leadership and candidate suitability.
It evaluates critical dark personality traits (Borderline, Machiavellian, Narcissistic, Psychopathic, and Sociopathic), providing a clear picture of each candidate’s strengths, risk factors, and potential impact on team dynamics. By identifying early signs of leadership toxicity, TGS helps recruiters go beyond traditional interviews and résumés to make evidence-based hiring decisions that protect organizational culture and enhance long-term performance.
Using the ASCA Model—Anxiety, Stimulation, Conformity, and Ambiguity—TGS reveals how candidates behave under pressure, adapt to change, and align with your organization’s values and expectations. This holistic approach enables you to place not just skilled candidates, but the right leaders who will inspire trust, collaboration, and productivity.
With TGS, recruiters can minimize hiring risks, improve leadership placements, and strengthen client confidence through scientifically backed behavioral insights.

Taking The Assessment
The assessment consists of 173 questions, and it takes less than 25 minutes to complete. It is forensically checked for respondent authenticity. If there is any concern about authenticity, the participant will be asked to retake the assessment.
Authenticity Check
One of the key ways we are different from other assessments is our ability to ensure respondents are telling the truth.
Leadership Insights
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum
Performance Personalities
The reason leaders 'get stuff done'
The performance personalities of Borderline, Machiavellianism, Narcissism, Psychopathy, and Sociopathy are crucial for effective leadership. They provide traits that enable decisive action, strategic ruthlessness, charismatic confidence, and intense motivation. The GreyScale Assessment identifies these personalities as dynamic (effective/green), diluted (ineffective/amber), or dangerous (risky and toxic/red).
