Junior Tennis Development Programme: Croatia

1. Programme Overview & Philosophy

The Croatian Tennis Association (Hrvatski teniski savez - HTS) operates as the overarching governing body for tennis in Croatia, established on June 13, 1912, in Zagreb. As a non-profit legal entity, it is registered with the relevant state administration bodies for associations and sports activities within the Republic of Croatia. The HTS is a full member of the International Tennis Federation (ITF), Tennis Europe (TE), and the Croatian Olympic Committee (HOO), ensuring its operations align with the Law on Sport, the Law on Non-Profit Associations, and the Olympic Charter [1].

The core philosophy of the HTS is centered on fostering the continuous growth and advancement of tennis across all levels, from junior and children's categories to professional and recreational activities. The association is committed to promoting tennis as an accessible sport for the wider population, with a particular emphasis on integrating children and young people into structured programs that ensure broad participation and long-term sustainability. A central tenet of their operation is the establishment of a system that facilitates the achievement of top-tier athletic results. This involves providing high-quality infrastructure, expert coaching, and clear support programs for players, enabling Croatian tennis players to compete at the highest international levels. The HTS also actively promotes collaboration among its members—clubs, county associations, and other organizations—recognizing that a unified strategy and coordinated efforts are fundamental to stable development [1].

2. Governing Body & Structure

The Croatian Tennis Association (Hrvatski teniski savez - HTS) is the official governing body for tennis in Croatia. Its organizational structure includes an Executive Director, a Sports Coordinator, and various administrative and specialized staff. The association is governed by a Management Board, a Supervisory Board, and a Disciplinary Court. The HTS also has a Professional Board, which includes national selectors for various age categories, such as U12/U14 (male and female), U16/U18 (male and female), and senior teams [1].

The HTS coordinates activities with county tennis associations and numerous tennis clubs and associations throughout the country. This decentralized yet coordinated approach aims to ensure a consistent development pathway and broad reach across Croatia. Funding for the HTS programs primarily comes from the Croatian Olympic Committee (HOO), dedicated sponsor funds, and the HTS's own resources. Additional funding for specific programs, such as the Croatia Tennis Pro Tournaments (CTPT), is also sourced from the Ministry of Tourism and Sport and local government bodies [2].

3. Development Pathway Stages

The HTS focuses on a structured development pathway, particularly emphasizing junior categories. While specific names for each stage from beginner to elite are not explicitly detailed as distinct stages, the annual program highlights activities for U12, U14, U16, and U18 categories, indicating a progression through these age groups. The emphasis is on providing structured training camps, national team selections, and participation in national and international competitions appropriate for each age level [1, 2].

4. U12 Training Model

The Croatian Tennis Association places significant importance on the U12 category, recognizing it as a crucial stage for talent development. The 2026 annual program mentions a training camp organized by the HTS in Vrsar specifically for U12 male and female tennis players. This indicates a centralized approach to early talent development, providing a structured environment for young athletes. The program also highlights the success of the U12 girls' national team, which achieved third place in the Winter Cup and fifth place in the Summer Cup, demonstrating a focus on team competitions at this age. Polina Car, Ana Marija Rebić, Jan Celišćak, Jakov Ogrizek, and Marta Barišić were noted for their participation in the European Masters U12, a competition for the top 32 young European players, with Polina Car and Ana Marija Rebić winning the doubles title. This suggests a strong emphasis on competitive exposure at a high level for U12 players [2].

While specific weekly training hours for tennis and physical conditioning, session structure, ball types used, and coach-to-player ratios are not explicitly detailed in the official HTS documents, a research study on young tennis players in the U12, U14, and U16 age categories in Croatia indicates varying training volumes. For U12 players, weekly tennis training hours for girls range from 7 to 24 hours, while physical training hours for boys range from 3 to 12 hours [3]. The mention of dedicated training camps and national team activities implies a structured and intensive program. The success at European level competitions further suggests a robust training model that prepares players for international standards. The appointment of Nikša Đurović as the U12/U14 female national selector and Vedran Orešković as the U12/U14 male national selector underscores the specialized coaching attention given to these age groups [2].

5. U14 Training Model

For the U14 category, the HTS continues to build upon the foundation laid in the U12 stage, with a clear progression towards more advanced competition and training. The same national selectors, Nikša Đurović for females and Vedran Orešković for males, oversee both U12 and U14 age groups, ensuring continuity in the development philosophy. The program highlights Korana Barišić's achievement of reaching the semi-finals of the European Championship U14 as an incoming year player, signifying the program's ability to develop players capable of performing at a high international level. The participation in European Masters for U12 players, who then transition to U14, indicates a continuous pathway for talented individuals [2].

The intensity of training is expected to step up from U12, aligning with the increased demands of international junior tennis. For U14 players, weekly tennis training hours for girls range from 15 to 40 hours, and physical training hours for boys range from 3 to 15 hours [3]. The focus on European Championships and Masters events suggests a commitment to rigorous preparation. The balance between academy and club training is not explicitly detailed, but the HTS's role in organizing national team activities and training camps implies a centralized component that complements club-based training. The overall objective is to prepare players for the U16 and U18 categories and ultimately for professional tennis [2].

6. Physical Development & Multi-Sport

The provided documents do not offer explicit details on the program's approach to physical literacy or the encouragement of multi-sport activities. However, the general objectives of the HTS, which include promoting tennis and ensuring the development of top-tier athletes, implicitly suggest that physical development is an integral part of the training regimen. High-performance tennis demands a strong physical foundation, and it is reasonable to infer that physical conditioning is incorporated into the training programs for junior players, especially as they progress through the U12 and U14 categories towards more competitive levels. The presence of a Sport Science and Medicine & Development Committee within the ITF and Tennis Europe, with Croatian representation (Petar Barbaros), indicates an awareness and potential integration of scientific approaches to physical development within the broader tennis ecosystem [1, 2].

7. Competition Structure

The Croatian Tennis Association maintains a comprehensive competition structure designed to provide players with ample opportunities for development and progression. The annual program outlines a calendar of national and international tournaments across various age groups. For junior players, this includes participation in Tennis Europe events and ITF Junior tournaments. The HTS also organizes national championships for individuals and teams, as well as Masters tournaments for U13 and U15 categories. The Croatia Tennis Pro Tournaments (CTPT) also provide opportunities for domestic players to compete at a professional level within Croatia, reducing travel costs and offering local support. The calendar of tournaments is flexible, adapting to organizational capacities and weather conditions, with the goal of optimizing planning and maintaining competition quality. The HTS aims to ensure a continuous series of professional tournaments at different levels to meet the needs of all players and facilitate progressive development through a systematic competitive pathway [2].

Players qualify for international events through their national rankings and performance in domestic and international tournaments. The success of Croatian junior players in European championships and Masters events demonstrates the effectiveness of this competition structure in preparing them for higher levels of play [2].

8. Coach Education

Coach education is a priority for the Croatian Tennis Association, with a focus on professionalizing the coaching system. The HTS plans to continue its efforts in 2026 to ensure all national selectors have valid contracts, stable incomes, and clearly defined work plans. The Association of Croatian Tennis Coaches (ZTTH) is responsible for enhancing professional coaching through the organization of coaching congresses and systematic coach licensing. The coach licensing regulations are aligned with the Law on Sport within the Ministry of Tourism and Sport, with all planned activities expected to be implemented during 2026. A professional seminar—the Congress of Croatian Coaches—is planned, covering all member coaches of the ZTTH. The thematic content of the congress will be determined by the ZTTH Assembly, with lectures delivered by experienced ZTTH coaches and external experts. Continuous education for all coaches is emphasized, with the aim of ensuring professional development, knowledge exchange, and strengthening the competencies of Croatian coaches. This systematic approach aims to raise the quality of work with players of all age groups and ensure the long-term competitiveness of Croatian tennis at national and international levels [2].

9. Talent Identification

Talent identification in Croatia begins at early age categories, as evidenced by the success of U12 players in European Masters events. The HTS organizes training camps for U12 players, indicating a proactive approach to identifying and nurturing young talent. The appointment of dedicated national selectors for U12/U14 age groups (Nikša Đurović for females and Vedran Orešković for males) further underscores the structured approach to talent identification and development. These selectors are responsible for coordinating work plans, monitoring players, and creating individual development plans [2].

The success of players like Korana Barišić (U14 European Championship semi-finalist), Emanuel Ivanišević (best Croatian junior representative), and Dora Mišković (top-ranked Croatian junior on ITF) suggests that the talent identification system is effective in recognizing and supporting promising young athletes. The inclusion of players in HOO development programs (I, II, IV, and HON - Croatian Olympic Hopes) based on their results and achievements further highlights the structured pathway for identified talents to receive additional funding and support [2].

10. Notable Achievements & Players

Croatia has a rich history of producing world-class tennis players, and the current development system continues this tradition. The 2025 analysis highlights several notable achievements and players:

• Petra Marčinko: Made significant progress on the WTA Tour, climbing from 257th to 114th in the world rankings, re-entering the top 150 [2].
• Dino Prižmić: Despite injuries, showed exceptional perseverance and quality, jumping from 292nd to 127th on the ATP rankings, nearing the top 100 [2].
• Antonia Ružić: Achieved remarkable progress, breaking into the top 100 female tennis players worldwide [2].
• Luka Mikrut: Rose from 399th to 162nd on the ATP rankings, confirming his trajectory towards the world elite [2].

• U12 Girls National Team: Achieved third place in the Winter Cup and fifth place in the Summer Cup, ranking among the best European national teams [2].
• Ana Petković: Continues to achieve excellent results, winning ITF J100 in Dubrovnik and ITF J60 in Maribor, and breaking into the top 250 juniors worldwide at just 16 years old [2].

These achievements demonstrate the effectiveness of the Croatian development system in nurturing talent from a young age and preparing players for success at both junior and professional levels. The consistent presence of Croatian players in international rankings and major tournaments reflects a robust and well-structured development pathway.

11. Key Lessons for Ireland

Based on the Croatian junior tennis development program, several key lessons could be valuable for Tennis Ireland:

1. Centralized Junior Development and National Selectors: The Croatian model emphasizes dedicated national selectors for specific junior age groups (U12/U14, U16/U18) who coordinate work plans, monitor players, and create individual development plans. This structured approach ensures continuity and specialized attention for young talents. Tennis Ireland could benefit from establishing similar dedicated roles and clear responsibilities for junior age group selectors, fostering a more cohesive and targeted development pathway.

2. Early International Exposure and Team Competitions: Croatia actively involves its U12 players in European Masters and team competitions like the Winter and Summer Cups. This early exposure to high-level international competition, combined with dedicated training camps, appears to be a significant factor in their junior success. Tennis Ireland could explore increasing opportunities for its younger junior players to participate in more international team events and structured training camps to accelerate their development and competitive experience.

3. Professionalization of Coaching and Continuous Education: The HTS places a strong emphasis on the professionalization of its coaching staff through systematic licensing and continuous education via congresses and seminars. This commitment to ongoing coach development ensures that players receive high-quality instruction aligned with national and international standards. Tennis Ireland could strengthen its coach education programs, focusing on regular professional development, knowledge exchange, and ensuring that coaching qualifications are consistently updated and aligned with best practices.
