What Is the Cebeci Test of Creativity (CTC)?

Quick answer The Cebeci Test of Creativity (CTC) is a standardized, non-verbal, computerized creativity assessment for grades Pre-K through 12. It measures four creativity dimensions — fluency, flexibility, originality, and elaboration — plus an overall percentile, in 30 minutes with no teacher scoring time. The CTC is protected by US Patent 12,087,176 and included free with Renzulli Learning.

Renzulli Learning offers an exclusive digital creativity assessment, the Cebeci Test of Creativity (CTC), a novel computerized assessment tool designed to address the limitations of traditional open-ended paper-and-pencil creativity tests like the Torrance Tests of Creative Thinking (TTCT). The CTC eliminates the time, cost, and consistency problems of manual scoring and brings creativity assessment into the modern, digital classroom.

Here’s why the CTC stands out among creativity assessments:

Significant cost & time savings: The CTC is more cost-effective and offers faster evaluation because Renzulli Learning, not teachers, handles the scoring — providing major time and cost savings for school districts.

Equitable & inclusive design: The CTC is culture-independent, fully figural (no text outside the tutorial), and supports multiple languages, making it uniquely suitable for diverse, low socioeconomic, and at-risk student populations as well as English language learners.

Comprehensive creativity measurement: The CTC precisely measures all four critical creativity domains: fluency, flexibility, originality, and elaboration.

Detailed creativity reports: Available to designated administrators and teachers, these reports provide four-dimension creativity percentiles and an overall score for students, classrooms, schools, and districts.

The CTC is currently included with Renzulli Learning at no additional cost. Once your school subscribes to Renzulli Learning, every teacher can administer the CTC to every student — identifying creative talent and then developing it through the platform’s 40,000+ inquiry-based enrichment activities.
The four creativity dimensions

What Does the Cebeci Test of Creativity Measure?

The CTC measures creativity through four distinct dimensions, each scored as a percentile against grade-level norms, plus an overall creativity percentile:

Fluency

The number of relevant ideas a student generates in response to a creative prompt.
Idea quantity

Flexibility

The ability to produce a variety of different ideas, categories, or approaches.
Idea variety

Originality

How novel or unique the student’s ideas are compared to peers.
Idea novelty

Elaboration

The level of detail, refinement, and development in each idea.
Idea depth

How to interpret CTC scores: Students at the 85th–94th percentile are considered Highly Creative. Students at the 95th percentile and above are deemed Exceptionally Creative. Districts may set their own thresholds — for example, the 98th percentile to identify the top 2% of students for specialized gifted programs.

Getting started

How Do I Take the CTC?

Administering the CTC takes three steps from your Renzulli Learning Teacher dashboard:

Step 1 — Log in: Sign into your Renzulli Learning Teacher dashboard at login.renzullilearning.com.
Step 2 — Find the CTC panel: Scroll down until you see “Cebeci Test of Creativity” on the right side of your screen.
Step 3 — Launch the assessment: Click the button “Click Here to Take the CTC.” The assessment runs entirely in the browser, and results are scored automatically.
From identification to development: Identifying creative ability is only the first step. Once the CTC surfaces a student’s creative profile, Renzulli Learning’s 40,000+ inquiry-based, interest-matched activities give educators concrete tools to develop and strengthen that creativity. As the three-year UConn study showed, students using SEM Type 3 activities through Renzulli Learning experienced dramatic gains on the CTC over time.
Frequently asked questions

Cebeci Test of Creativity: Common Questions

The Cebeci Test of Creativity (CTC) is a standardized, non-verbal, computerized creativity assessment for students in grades Pre-K through 12. It measures four creativity dimensions — fluency, flexibility, originality, and elaboration — plus an overall creativity percentile. The CTC is fully figural (no text outside the tutorial), supports multiple languages, can be administered in 30 minutes, and is computer-scored. The CTC is protected by US Patent 12,087,176 and included free with Renzulli Learning.
The CTC scores students across four dimensions: fluency (number of relevant ideas), flexibility (variety of different ideas or approaches), originality (novelty or uniqueness of ideas), and elaboration (level of detail and development). Each dimension is converted into a percentile against grade-level norms, plus an overall creativity percentile. Common interpretation: 85th–94th percentile = Highly Creative; 95th percentile and above = Exceptionally Creative. Districts may set their own thresholds, such as the 98th percentile to identify the top 2% for gifted programs.
The CTC was developed by Dr. Sukru Murad Cebeci and validated in peer-reviewed research published in the Journal of Creative Behavior (Cebeci & Acar, 2025). A three-year longitudinal study by Milan, Reis, Cebeci, and Maraschi at the University of Connecticut documented dramatic gains in creativity scores when the CTC was used alongside Renzulli Learning’s Schoolwide Enrichment Model (SEM) Type 3 activities. Renzulli Learning holds US Patent 12,087,176 for the CTC method and system.
The CTC is available for students in grades Kindergarten through 12. Younger students might need assistance from their teacher to read the text in the tutorial section, but the actual test is fully visual and figural — no reading required.
The CTC can be administered in 30 minutes. Because it is computer-administered and computer-scored, there is no teacher scoring time required — generating substantial time and cost savings compared to traditional paper-and-pencil creativity assessments like the Torrance Tests.
Three steps: (1) Log in to your Renzulli Learning Teacher dashboard at login.renzullilearning.com; (2) Scroll down until you see “Cebeci Test of Creativity” on the right side of your screen; (3) Click the button “Click Here to Take the CTC” to launch the assessment.
Renzulli Learning activities are research-proven to increase creativity, so we recommend testing every year to monitor student creative development. If the purpose is screening or identification, schools typically don’t retest. Some schools retest annually to monitor growth, and some schools in Italy use the CTC for pre- and post-semester evaluation, retesting six months after the initial assessment.
The CTC is more cost-effective, offers faster evaluation through computer scoring, is culture-independent, suitable for diverse and at-risk students, fully figural (no text outside the tutorial), supports multiple languages, and measures all four creativity domains (fluency, flexibility, originality, elaboration). Unlike traditional paper-and-pencil tests such as the Torrance Tests of Creative Thinking (TTCT), the CTC eliminates manual scoring entirely and is included at no additional cost with Renzulli Learning.
Yes. The CTC is specifically designed to identify highly creative students in underserved populations who are often overlooked by traditional intelligence tests. Because it is non-verbal, fully figural, culture-independent, and multilingual, it works particularly well with English language learners, students from low socioeconomic backgrounds, and culturally diverse populations — supporting equity and inclusion in gifted identification.
Identifying creative ability is only the first step. Renzulli Learning provides over 40,000 inquiry-based, interest-matched enrichment activities that develop and strengthen students’ creativity using their own interests as the engagement driver. The three-year University of Connecticut study (Milan, Reis, Cebeci, & Maraschi) showed that students using SEM Type 3 activities through Renzulli Learning experienced dramatic gains on the CTC — confirming that the CTC and Renzulli Learning together both identify and grow creative talent.
