परीक्षण की विश्वसनीयता का अर्थ है कि कोई परीक्षण लगातार और स्थिर परिणाम प्रदान करता है, यानी यदि किसी व्यक्ति को समान परिस्थितियों में दो या अधिक बार परीक्षण किया जाए तो परिणामों में अधिक परिवर्तन नहीं होना चाहिए। यह सुनिश्चित करता है कि परीक्षण में प्राप्त अंक वास्तविक रूप से उस व्यक्ति की क्षमता, ज्ञान या कौशल का प्रतिबिंब हों, न कि आकस्मिक या बाहरी कारकों का परिणाम। विश्वसनीयता केवल परीक्षण के स्कोर की स्थिरता और सटीकता को दर्शाती है, और यह यह भी बताती है कि परिणाम कितने भरोसेमंद हैं। किसी परीक्षण की विश्वसनीयता जितनी अधिक होगी, उतनी ही उस पर आधारित निर्णयों की वैधता और न्यायसंगतता अधिक होगी। परीक्षण की विश्वसनीयता मापन के लिए विभिन्न तरीकों का प्रयोग किया जाता है, जिनमें प्रमुख हैं: परीक्षण-पुनर्परीक्षण (टेस्ट-रिटेस्ट मेथड) और समान्तर रूप विधियाँ (पैरेलल फार्म मेथड)। परीक्षण-पुनर्परीक्षण विधि में वही परीक्षण किसी समूह पर एक निश्चित अंतराल के बाद पुनः लागू किया जाता है। उदाहरण स्वरूप, यदि एक समूह छात्रों को गणित का परीक्षण दिया जाता है, तो कुछ हफ्तों बाद वही परीक्षण उन्हें पुनः दिया जाता है। इसके बाद दोनों
