為何要考取 SAS 國際專業證照呢？當初想法很簡單就是透過考取 SAS 國際專業證照的過程中有系統的學習 SAS 解決方案，當然在學習的過程中有遇到許多困難，但是比起工作上所面臨現實妥協和實務壓力，有機會持續學習新事物對於我來說是另一種維持工作的熱情和紓解壓力的方式吧！若是初學者則建議先考取「SAS Certified Base Programmer for SAS 9」、「SAS Certified Advanced Programmer for SAS 9」和「SAS Certified Visual Business Analyst: Exploration and Design Using SAS Visual Analytics」這三張證照，但是這三張證照目前已經有推出全新的考試方式，分別為「[SAS Certified Specialist: Base Programming Using SAS 9.4](https://www.sas.com/en_us/certification/credentials/foundation-tools/base-programming-specialist.html)」、「[SAS Certified Professional: Advanced Programming Using SAS 9.4](https://www.sas.com/en_us/certification/credentials/foundation-tools/advanced-programming-professional.html)」和「[SAS Certified Specialist: Visual Business Analytics 7.5/8.3](https://www.sas.com/en_us/certification/credentials/bi-analytics/visual-business-analytics.html)」，主要以實機操作的方式來測驗對於撰寫 SAS 程式的熟悉程度，建議參考 [Coursera 的線上課程](https://www.coursera.org/professional-certificates/sas-programming)有系統的學習撰寫 SAS 程式的專業知識，以及對於商業分析報表有基本探索和設計的操作概念。此外不論是撰寫 SAS 程式或探索和設計報表皆是透過 SAS 解決方案進行資料分析應用最關鍵且最基礎的專業技能，我們能夠透過 SAS Enterprise Guide 或 SAS Studio 撰寫 SAS 程式碼快速進行資料處理，當資料處理完成之後，我們就能夠透過 SAS Visual Analytics 探索和設計報表，將資料以不同的視覺化方式呈現分析觀點。

接著若是分析專家則建議先考取「[SAS Certified Statistical Business Analyst Using SAS 9: Regression and Modeling](https://www.sas.com/en_us/certification/credentials/advanced-analytics/statistical-business-analyst.html)」和「[SAS Certified Predictive Modeler Using SAS Enterprise Miner 14](https://www.sas.com/en_us/certification/credentials/advanced-analytics/predictive-modeler-14.html)」這兩張證照，主要測驗透過 SAS 程式設計統計迴歸模型的熟悉程度，以及透過實機操作的方式來測驗對於透過 SAS Enterprise Miner 建立預測模型的熟悉程度，以及這兩張證照皆會需要了解和熟悉統計的專業知識，才能夠輕鬆考取，所以對非本科系的分析專家將會是一大挑戰，但只要有心學習也能夠通過測驗，建議參考 [Coursera 的線上課程](https://www.coursera.org/learn/sas-statistics)有系統的學習統計的專業知識。至於非本科系的分析專家，像是資訊人員則建議先考取「[SAS Certified Platform Administrator for SAS 9](https://www.sas.com/en_us/certification/credentials/administration/platform-administrator.html)」這張證照，這也是我第一張考取的 SAS 國際專業證照，主要測驗對於 SAS 平台中使用者管理和系統管理的熟悉程度，當時主要是維運 SAS 解決方案的平台，為了更有效管理 SAS 解決方案的平台，因此就先去考取這張 SAS 官方認證平台管理員證照，但是現實是僅僅考取證照是不足夠解決工作所面臨的實務問題，還需要持續閱讀官方文件和實際操作才能夠有效解決工作所面臨的實務問題。

再來若是資料科學家則建議先考取「[SAS Certified Big Data Professional Using SAS 9](https://www.sas.com/en_us/certification/credentials/data-management/big-data-professional.html)」、「[SAS Certified Advanced Analytics Professional Using SAS 9](https://www.sas.com/en_us/certification/credentials/advanced-analytics/advanced-analytics-professional.html)」、「[SAS Certified Specialist: Advanced Predictive Modeling Using SAS 9](https://www.sas.com/en_us/certification/credentials/advanced-analytics/advanced-analytics-professional/advanced-predictive-modeling-exam.html)」和「[SAS Certified Specialist: SAS Text Analytics, Time Series, Experimentation and Optimization Using SAS 9](https://www.sas.com/en_us/certification/credentials/advanced-analytics/advanced-analytics-professional/text-analytics-exam.html)」這四張證照，這四張證照總共有五科專業測驗，其中一科為「[SAS Certified Predictive Modeler Using SAS Enterprise Miner 14](https://www.sas.com/en_us/certification/credentials/advanced-analytics/predictive-modeler-14.html)」證照的專業測試，而當考取這四張證照之後，就會取得「[SAS Certified Data Scientist Using SAS 9](https://www.sas.com/en_us/certification/credentials/advanced-analytics/data-scientist.html)」這張證照，主要測驗大數據管理和進階分析的熟悉程度，大數據管理主要就是有關資料處理、資料統計、資料呈現、資料品質、… 等相關專業技能，當然也包括 Hadoop 平台的基礎專業知識，至於進階分析主要就是有關預測模型、深度學習、開放源碼、文字分析、時間序列、優化研究、科學實驗、…等相關專業技能，其中考試內容有許多理論概念。此外考試主要還是以 SAS 9 平台中的解決方案為主，所以需要對於 SAS 解決方案要有足夠的熱情，才能夠順利通過五科專業測驗取得 SAS 官方所認證的資料科學家證照。

最後若是人工智慧和機器學習專家則建議直接考取「[SAS Certified Specialist: Machine Learning Using SAS Viya 3.4](https://www.sas.com/en_us/certification/credentials/advanced-analytics/machine-learning-specialist.html)」、「[SAS Certified Specialist: Forecasting and Optimization Using SAS Viya 3.4](https://www.sas.com/en_us/certification/credentials/advanced-analytics/forecasting-and-optimization-specialist.html)」和「[SAS Certified Specialist: Natural Language & Computer Vision Specialist Using SAS Viya 3.4](https://www.sas.com/en_us/certification/credentials/advanced-analytics/natural-language-computer-vision-specialist.html)」這三張證照，這三張證照總共有三科專業測驗，而當考取這三張之後，就會取得「[SAS Certified Professional: AI and Machine Learning](https://www.sas.com/en_us/certification/credentials/advanced-analytics/ai-machine-learning-pro.html)」這張證照，主要測驗機器學習、自然語言分析、電腦視覺、預測分析和優化研究的熟悉程度。至於要如何有系統的學習，建議參考 [Coursera 的線上課程](https://www.coursera.org/learn/machine-learning-sas)有系統的學習機器學習的專業知識，更進一步建議參加[官方專業訓練課程](https://www.sas.com/zh_tw/training.html)，因為基本上考題 90% 皆是專業訓練課程的教學內容，考得非常詳細，所以若沒有熟悉和深入了解專業訓練課程的教學內容將很難通過考試，尤其是 10% 的內容需要額外讀取相關文獻。此外範例考題基本上完全一樣的題目皆不會出為考題，但是會有幾題是變化題，所以背範例考題沒什麼幫助，必須真的了解答案背後所代表的意義和相關章節要非常熟悉，才能夠順利通過三科專業測驗取得 SAS 官方所認證的人工智慧和機器學習專家證照。

總結考取證照基本上僅是學習過程的證明，更重要的是我們要如何根據所學的專業知識為客戶提供最專業的顧問服務，以及解決客戶所面臨的現實問題，更進一步根據不同的客戶需求提供最適合的解決方案，以利為企業組織帶來更高的商業價值。
